Surface Treatment of Aluminum at Mastec CCTech

At CCTech in Ulricehamn, we specialize in surface treatment for small to medium-sized series. With a modern and highly automated machinery fleet, we can work both efficiently and with high precision—ready to meet tomorrow’s demands today.

We are known for our fast delivery capability. The standard lead time is only 5 days, and historically we have in some cases been able to meet customers’ needs in times down to 3 hours. Our success factors are continuous inspections, carefully documented processes, and an uncompromising focus on quality.

Surface treatments we offer include anodizing, passivation, and chromating of aluminum. We also perform tumbling and assembly and can deliver finished products directly to the end customer. Flexibility is one of our most important guiding principles—and something we live by in every assignment.

Anodizing of Aluminum

Anodizing is a surface treatment method that significantly increases aluminum’s resistance. Through a controlled electrolytic oxidation process, the surface is converted from pure aluminum to durable aluminum oxide.

The result is components that are dirt-repellent, have high wear resistance, are electrically insulating, and receive effective corrosion protection, even in demanding environments. At the same time, the surface becomes more decorative.

We can anodize parts up to 2100 × 550 × 950 mm. We offer several color options, including natural, black, green, red, and blue.

Hard Anodizing for Wear-Resistant Components

When the application requires an extra wear-resistant surface layer, hard anodizing is the obvious choice. The method differs technically from conventional anodizing in that higher electrical voltage and current are used, creating a surface layer with higher oxide content.

The pores become fewer and smaller, resulting in an even harder and more durable surface. Hard anodizing is often used in industries such as aviation, hydraulics, and medical technology.

We offer hard anodizing in the colors natural, green, blue, and red.

Chromital – Corrosion Protection According to MIL 5541

CCTech offers surface treatment according to Chromital Surtech 650 TCP and is one of few approved suppliers in this area. We meet the military standard MIL 5541, and the method provides very high corrosion protection for both treated and untreated aluminum parts. Our surface-treated components pass 168 hours of corrosion testing in salt spray according to ASTM B-117.

Quality, Environment, and Certifications

At CCTech, quality and environment are central parts of our operations. We conduct frequent and structured bath analyses, follow supplier recommendations, and work according to our process manual.

We measure TOC (Total Organic Carbon) at a detailed level and maintain process logs along the entire line. All process statistics are monitored through daily management and regular meetings. CCTech is certified according to ISO 9001 and ISO 14001.
