Titanium Components Supplied To The Aerospace Industry

We are proud to supply the aerospace industry, helping businesses within aerospace engineering to flourish with a supply of our high-quality components manufactured from titanium (Ti).

We offer tailored advice on special metals from real engineers, helping to guide our customers to make the most valuable purchases. Often, within aerospace, the solution is the use of titanium. For use with extremely high and low-temperature fluctuations, and of course, the importance of strength to weight ratio.

The popularity of using titanium within aerospace projects sparked in the US around the time of the Cold War. The military was scouting for a durable material with very specific capabilities, that gradually worked its way into the commercial aerospace industry.

This wasn’t only happening within the US, but the UK aerospace industry was also starting to implement titanium components, framework, and more, with knowledge of the materials fantastic benefits. Titanium is one material that fits the aerospace industry like a glove!

Advantages of Titanium

Why has titanium become such a widely adopted material for the aerospace industry? By looking at the properties of titanium, you’ll find the answer.

Titanium has great durability in areas of low temperature
Titanium has great durability at extremely high temperature

Titanium is a lightweight alloy when compared to alternatives
The high strength properties of titanium make it a worthy long-term investment
High corrosion resistances – especially oxidation because of the immediate forming of a coating upon exposure to air

Uses of Titanium

Listed examples of what titanium is used for (but not limited to!) :

Aircraft engine manufacture
Applications requiring lightweight solutions
Frames
Discs
Blades and shafts
Aircraft hydraulic systems
Armor plating and defence industry equipment
Propellers
Fan blades
Parts for landing gear

UK Supplied Titanium Components

Waverley Brownall is proud to supply the UK aerospace industry with the necessary components for on-going projects.

Our components are manufactured from Titanium, machined via highly technically-capable CNCs, accompanied at all times by experienced engineers.

These are then supplied to our customer, with fast delivery options available and a high-flexibility that our competitors don’t offer.

We also specialise in the manufacture of bespoke titanium products.

5 Impressive Corrosive Resistant Alloys

Corrosion is described as, “A natural but controllable process” by Gretchen Jacobson (Managing Editor of Materials Performance for NACE International.)

It is a naturally occurring problem, the deterioration of materials due to chemical reactions in the surrounding environment.

Corrosive Resistant Alloys

1. 6Mo Austenitic Stainless Steel (UNS S31266)

The metal 6Mo is often referred to as super-austenitic. This type of stainless steel covers grades with high chromium, nickel and molybdenum content. 6Mo is an alloy that was designed specifically for metallurgical stability and resistance against corrosive substances.

Strengths: Seawater and Organic acids

2. Inconel 625 (UNS N06625)

Strengths: Organic acids, alkaline and salts, seawater, sulfuric and nitric acid

3. Hastelloy C-276 (UNS N10276)

Strengths: Organic acids, alkaline and salts, seawater, sulphuric acid, hydrochloric, hydrofluoric and phosphorus acid, chlorine (wet).

4. Titanium (Grade 2 | UNS R50400)

Strengths: Chlorine (wet), uses for strength to weight ratio, alkaline, salts and seawater.

5. Monel 400 or Alloy 400 (UNS N04400)

Strengths: Seawater, salts and hydrofluoric acid.

The Fight Against Corrosion

Corrosion is a problem for many industries, including the Department of Defence, Energy, Oil and Gas production and transfer – including pipelines.

The industry of water and wastewater is also affected; both public and private companies must protect assets against corrosion.

These assets are main parts of the infrastructure for wastewater plants, such as reservoirs, pumping plants and distribution pipelines – even storage.

The materials that are used in order to fight corrosive media is essential for preventing system failures and other hazardous matters.

Tube Fittings Material Selection

Tube fittings material selection can be a tricky process, where cost and availability are at the forefront for many industries.

Quick tip: Charts for aqueous corrosion resistance and material composition can be found on our special metals page.

Tube Fittings Material Selection

All products from our compression Tube fittings (single and double) range are available in special metals.

Other products that can be manufactured include pipe fittings for high or low pressure applications and valves for full flow control of media.

Material	Features	Availability
316 Stainless Steel	Most commonly specified material for a range of environments	Immediate with next day delivery
6MO Stainless Steel	Pitting, crevice corrosion and strength increased from 316	Moderate stocks
Monel 400	Great choice for general seawater application. Popular with pump manufacturers.	Moderate stocks
Duplex SS	A natural step-up from 316 and 6MO	Moderate stocks
Super Duplex SS	Fantastic atmospheric corrosion	Moderate stocks
Incoloy 825	Outstanding resistance in reducing environments, used extensively in chemical processing	Immediate and Moderate
Inconel 625	High strength, excellent corrosion resistance and welding abilities	Deliveries less than 8 weeks
Hastelloy C276	Outstanding corrosion resistance. Almost unmatched in seawater application especially under crevice conditions which would attack 316, 6MO and Monel 400.	Immediate for popular size fittings and Moderate material stock
Titanium	Excellent strength, corrosion resistance and used extensively in the aerospace and automotive industries. Outstanding all-round resistances.	Manufacture-to-order, no more than 6 weeks

Tube Material Selection

Tubing Material	General Application	Rec. Temp Range*
316 Stainless Steel	High pressure, High Temperature, Generally Corrosive Media	-225C to 605C
Monel 400	Recommended in Sour Gas, Marine and Chemical application	-198C to 425C
Hastelloy C-276	Excellent corrosion resistance to Oxidizing and Reducing Media	-198C to 535C
Titanium	Resistant to Many Natural Environments such as Seawater and Salt solutions	-59C to 315C

Main Considerations When Selection The Right Material

Media (Internal)
Environment (External)
Intended Application and Process
Strengths and possible Weaknesses
Cost effectiveness (Selecting a special metal over 316 stainless steel is often considered a long-term investment. Costs for maintenance are dramatically reduced.)
Availability
Health and Safety Regulations

Corrosive Environments

Possible corrosive environments are a key factor for the durability of tube fittings and pipe fittings. Certain materials will cope better than others when faced with the different types of corrosion.

You will need to find out the effectiveness of the materials you are considering for your fittings against main consideration factors. (Media, environment, strengths, cost effectiveness, availability, safety…)

Corrosion By Acids

*Chart is to be used as a guideline only. Please discuss with us the internal media and external environment for your tube and pipe instrumentation.

Acidic Media	Resistance Material Choices
Sulphuric	6M0 (When the temperature is moderate and concentration is over 65%) Incoloy 825 (Good general resistance) Hastelloy C276 or Inconel 625 (At higher temperature ranges)
Hydrochloric	6M0 (Diluted) Incoloy 825 (Diluted) Inconel 625 (Diluted) Hastelloy C276 (The best choice with aggressive solutions)
Phosphoric	6M0 (Pure phosphoric) Incoloy 825 (Recommended – holds resistance to pure phosphoric at all concentrations and temperatures up to boiling 85%) Hastelloy C276 and Inconel 625 (In the presence of chlorides and fluorides)
Nitric	Incoloy 825 (Resistance to solutions up to boiling 65%) Inconel 625 Titanium

The Main Considerations In Acidic Corrosion Resistance
