Anodising

Aluminium Anodising Services in Sydney, Melbourne and Australia wide

Anodised aluminium offers a durable protective coating for a wide range of products and industries. An electrolytic surface treatment process, anodising develops a tough aluminium oxide film over the surface of the treated part to create an aesthetically pleasing and hard-wearing finish for a wide range of products such as engineering parts, architectural fittings, appliances such as fridges, pans and more.

• Corrosion-resistant: anodising converts the surface of the base material into a protective coating resistant to water, moisture and rust
• Scratch-resistant: High wear resistance and ability to withstand abrasion
• Non-chip: the coating becomes part of the metal itself, and cannot chip or blister
• Graffiti-resistant: graffiti marks will wipe off with a damp cloth
• Chemical-resistant: can stand up to mild acids
• Interior or exterior applications: can be used across a wide range of products
• Australian Made: DECO is entirely Australian owned and operated

Frequently Asked Questions

What lengths of material can I anodise?

DECO can anodise products up to 2800mm long, 1000mm deep and 400mm wide.
Our second rack (clear anodising only) can anodise products up to 3000mm long, 1200mm deep and 600mm wide.

Can my anodised products be coloured?

Because the aluminium surface formed on the product is porous, it is possible for dyes to seep into the pores of the aluminium. Parts can also be coloured electrolytically. Please check our colours page for our available anodising colours.

What is the thickness of anodising?

Standard anodising is around 5-20 microns. For hard anodising with a thickness of 50-100 microns, click here.

Can you anodise aluminium alloys?

Alloyed aluminium can compromise the anodised finish as the metal contains impurities. The surface finish may be less effective, or discolour. If you choose to use an aluminium alloy, we recommend the 6000 series (preferably 6061) or higher. The higher the aluminium content in your alloy, the better. Alloys with low aluminium content (especially 2000 and 3000 series alloys) will not anodise as effectively.

Is anodising chemically resistant?

Anodising protects aluminium from mild acids, but can be attacked by alkali materials such as lime mortars and cement.

Is anodising heat resistant?

Anodising is generally heat resistant up to 800C. After this temperature there may be a risk of crazing.
