What is Anodising?
Anodising is a specialised process within the realm of anodic oxidation, and stands out for its unique combination of durability and aesthetic enhancement.
This electrochemical procedure transforms the surface of aluminium alloys into a decorative, corrosion-resistant, anodic oxide finish, which is integral to the metal.
The process involves submerging the aluminium into an acid electrolyte bath and passing an electric current through the medium. This results in the aluminium oxide layer being built from the aluminium itself, emerging both from and on the aluminium as pictured below.
This oxide layer is not applied like paint or coating, but is fully integrated with the underlying aluminium substrate, so it cannot chip or peel. It provides increased resistance to corrosion and wear, significantly extending the lifespan of the product.
Type 2 Anodising
A key feature of type 2 anodising is the ability to add vibrant colors, provide medium level corrosion and insulation properties.
Through dyeing, the porous nature of the oxide layer can be exploited to colour the aluminum with a wide range of colors, enhancing its aesthetic appeal without compromising the protective qualities.
This makes it an ideal choice for a variety of applications of over 30 different industries, including marine, consumer electronics, automotive and motorsport parts, architectural components, defence and aerospace.
Type 2 anodising is not just a treatment; it's an investment in longevity and aesthetics. It's a perfect blend of form and function, ensuring that your products are not only visually striking but also durable and long-lasting.
Type 3 Hard Anodising
Type 3 anodising is known for its robust and hard-wearing finish, offers superior wear and corrosion resistance and it can be Teflon (PTFE) impregnated for increase lubricity and corrosion properties.
Ideal for high-wear applications, it significantly extends the lifespan of products. This process also allows for better heat dissipation, making it perfect for components exposed to extreme conditions or heavy usage.
Type 3 - PTFE Impregnation
Impregnation of PTFE (Polytetrafluoroethylene) or Teflon into Type 3 hard coat anodising is a process that enhances the properties of aluminum parts for higher corrosion resistance, wear resistance, and lowers coefficient friction (increased lubricity).
After creating a type 3 layer of aluminum oxide on the surface of the aluminium, the layer is then immersed into a PTFE solution, filling the microscopic pores in the anodised layer.
This creates a self-lubricating surface, reducing friction, and enhancing release characteristics. It finds applications in various industries, including aerospace and automotive, where parts require reduced friction, improved durability, and resistance to galling. This process improves the performance and longevity of aluminum components.
Titanium Anodising
Titanium anodising is a surface treatment process that enhances the properties of titanium metal. It involves immersing the titanium in an electrolytic bath and applying an electrical current. This creates an oxide layer on the titanium's surface, known as titanium dioxide. Anodising serves several purposes, including improving corrosion resistance, enhancing wear resistance, and providing decorative coloring options. Depending on the voltage and electrolyte used, different colors can be achieved, making it popular for aesthetic purposes in industries like jewelry and automotive parts. Titanium anodising also maintains the metal's biocompatibility, making it valuable in medical implants and aerospace applications, further aligning with your dedication to diverse industries.

Chromate Chemical Conversion
Chromate Conversion Coatings: Types 1 and 2
Chromate conversion coatings are chemical treatments applied to metal surfaces, primarily aluminum, to enhance corrosion resistance and prepare the surface for paint and other finishes. These coatings are categorized into Type 1 and Type 2, each with distinct characteristics and uses.
Type 1 Chromate (Hexavalent): This type offers exceptional corrosion resistance and durability. It's commonly used in aerospace, military, and automotive industries for its ability to form a thicker coating, providing a higher level of protection. The coating typically appears as a distinctive yellow, which also aids in identifying treated metals.
Type 2 Chromate (Trivalent): While it offers slightly less corrosion resistance compared to Type 1, it's more environmentally friendly and still provides adequate protection for many applications. This type is often used in electronics, general industry, and where compliance with environmental regulations is crucial. The coating usually has a clear to iridescent appearance and is a popular choice for visible consumer products.
Both types serve as a primer for additional coatings or paints, enhancing adhesion and preventing undercoat corrosion, making them vital in various industrial applications.
Stainless Passivation
Stainless steel passivation is a critical process that enhances the natural corrosion resistance of the material.
By removing surface contaminants and creating a thin, protective oxide layer, passivation prevents rust and pitting, crucial for maintaining the integrity and longevity of stainless steel components.
This process is particularly beneficial in environments prone to corrosion, such as those with high moisture or chemical exposure. Passivation also helps in maintaining the metal's aesthetic appeal, ensuring it retains its clean, shiny appearance. Ideal for a wide range of industries, from medical to food processing, to defence and aviation. Passivation is a key step in ensuring the durability and safety of stainless steel products.
