Hard Anodising Services in Auckland, New Zealand
ABOUT US
Ultimate Anodise has provided Type II and Type III hard anodising services from our West Auckland facility since 2009. Our tanks handle components from small machined fittings to structural extrusions up to 6 metres long. We work with Auckland fabricators, marine engineering firms, and manufacturers producing components for defence, medical, and industrial use.
Type III hard anodising is our specialty — a 60µm coating built to withstand heavy wear and extreme weather conditions. We also offer standard Type II at 12µm for architectural work, and a 25µm marine-grade process for components exposed to saltwater.
Standard turnaround is 5–10 working days, depending on coating type and current tank schedule. Faster turnaround is available for time-critical projects. Send us your drawings or component specifications for a detailed quote.
HOW IT WORKS
Anodising is an electrochemical process that converts the aluminium surface into aluminium oxide. The component becomes the anode in a sulphuric acid bath, and a controlled current is applied. The surface oxidises evenly, producing a coating that's roughly half into the metal and half above the original surface.
Type III hard anodising runs cold (around 0–5°C) at higher voltage than standard anodising, producing a denser, harder coating. We continuously monitor tank temperature, acid concentration, current density, and process time throughout each cycle. Getting any of these wrong results in soft coatings, uneven thickness, or surface burning.
Durability
Anodised products have an extremely long-life span and offer significant economic advantages through maintenance and operating savings.
Adhesion
Anodising is a reacted finish that is integrated and penetrated with the underlying aluminium for total bonding and unmatched adhesion.
Environment
Wastewaters are filtered and neutralized. The anodic layer remains 100% aluminium, so full recyclability is not compromised.
Niche Products
For components that require extra attention to detail, we have the knowledge and commitment to deliver the best solution possible.
Commitment
Committed to providing the highest quality finishes to meet client expectations as quickly and efficiently as possible.
Process Control
Precise combination of temperature, chemical concentration, proprietary catalysts and current density via sophisticated monitoring.
FIELDS OF APPLICATION
Providing anodising services to a wide and growing range of industrial sectors across New Zealand.
TYPE III HARD ANODISING
Type III is built for components under heavy mechanical load or in demanding environments. The 60µm coating provides excellent wear and corrosion protection, along with strong electrical insulation and high-temperature resistance. Full specifications on the services page.
- ■ Superior corrosion protection
- ■ Extreme wear resistance
- ■ Excellent electrical insulator
- ■ High temperature resistance
FREQUENTLY ASKED QUESTIONS
Cost depends on component size, batch quantity, and coating type. Type III costs more than Type II due to longer processing time and thicker coating. Production runs get better per-unit pricing than small batches. Call us on 09 836 8889 or send us your details for a quote.
Yes. Our West Auckland facility handles large components for marine, aerospace, and industrial work. Send us your dimensions and we'll confirm whether it fits.
