Aerospace is one of the most major industries in the UK today. And our aerospace surface treatments have become an integral part to the performance of aircraft components. This line of engineering refers to machineries such as aeroplanes, jets, space probes and ballistic missiles – every type of vehicle that’s designed to enter space from the interstellar medium down to the troposphere.

Furthermore, the military sector similarly relies on the abilities of our aerospace and defence coatings. Through intensive treatments and processing, we strive to reach the highest quality standard in every metal component that we anodise. Whether it’s Hard Anodising, Sulphuric Acid Anodising or Chromic Acid Anodising.

What parts can be anodised?

Anodising offers many advantages to metal surfaces. However, this is dependent on the part and what it requires.

Hard Anodising

Hard anodising aluminium is our most demanded-for service. Due to the intense use of parts, hard anodising offers a matchless aerospace surface treatment as it enhances insulation. When optimum heat dissipation is required, hard anodising can offer resistance and allow metal parts to withstand exposure to extreme temperatures. Therefore, aluminium is offered a longer and more reliable lifespan.

Chromic Acid Anodising

Another aerospace hard anodising technique is chromic acid anodising, as previously mentioned. This superior treatment matches aircraft components that require lapped joints, such as longitudinal skin splices. Chromic acid anodising is fantastic as an aerospace and defence coating as it offers immaculate anti-corrosion properties.

It excels in comparison to any other anodising type, especially when the fatigue strength of the aluminium substrate needs maintenance. Therefore, splices are again given a new lease of life, for longer.

Sulphuric Acid Anodising

Lastly, we have Sulphuric Acid Anodising as an aerospace surface treatment. Used for both Type II coatings and Type III coatings, depending on the requirements. Type III refers to those used in aerospace engineering. It works by treating aluminium alloy electrolytically to achieve a uniform anodic coating.

Again, this anodising treatment garners renown for its anti-corrosion properties and maximises durability on metal parts like wings and fuselage.
