BRUSHING
Brushing
Linear brushing using different grit, Van Gott type and Polishing
Ultraspec offers different aluminum brushing services to enhance surface finish of your materials and parts. Better than a time-saver brushing finish, we do linear manual brushing over a belt equiped table and Van Gott type brushing giving a blur and mat finish.
Application
Used on architectural extrusions and sheets, signs, boards, trophies, equipments and cabinets or furnitures.

What is Anodizing ?
Anodizing is an electrochemical process that converts the metal surface into an oxide finish.
At Ultraspec, we treat only aluminum even though nonferrous metals, such as magnesium and titanium, also can be anodized.
Our Process Types
Type I, Chromic Acid Anodizing (CAA)
First commercial type of anodizing, widely used in aerospace and defense. It minimises metal fatigue and is compatible with many aluminum alloys.
Type II, Sulfuric Acid Anodizing (SAA)
Most frequently used type of anodizing, this process will generate a decorative or protective surfaces with a greater durability than surfaces treated with type I.
Type III, Hardcoat Anodizing (HCA)
The primary objective of this process is to obtain a hard coating, resistant to abrasion. It is obtained using an electrolyte of sulfuric acid at low temperature with high voltage and current density.
BAC 5632 / MIL-A-8625 Boric Sulfuric Anodizing
Developed by Boeing Aerospace as a chrome free alternative to type I, for non-critical fatigue part. The adhesion to paint is equal or superior to Type I and this type of anodizing provides corrosion protection.
