aluminum used in architectural applications is anodized. • Increase abrasion resistance: The hard ano- dizing processes produce coatings from 25 ktm (1 mil) to more than 100 l, tm (4 mils) thick. These coatings, with the inherent hardness of aluminum oxide, are thick
Hardness of Hard-Anodized Aluminum Alloys. Figure 10 shows hardness of aluminum alloys before and after hard anodizing for 45 min in 17% sulfuric acid at
Under certain conditions of process and alloy, a Rockwell C hardness of 50 to 60 (520–700 HV) can be produced for Type III anodic coatings. A harder coating, and
Regular anodized aluminum with a softer coating has a hardness of about 200 to 400 HV, thus suitable for decorative purposes. Meanwhile, a typical hard coat anodize
Based on proven coil anodizing technology from our B57S product, B73A can be used for shelving, furniture, medical and domestic appliances and many other applications. Coil

Anodizing is an electrochemical method used to transform aluminum to aluminum oxide in the coating layer. Although being thin, this layer can substantially increase the abrasion and corrosion resistance of aluminum [ [1], [2],
aluminum used in architectural applications is anodized. • Increase abrasion resistance: The hard ano- dizing processes produce coatings from 25 ktm (1 mil) to more than 100 l, tm (4 mils) thick. These coatings, with the inherent hardness of aluminum oxide, are thick enough for use in applications involving rotating parts
Based on proven coil anodizing technology from our B57S product, B73A can be used for shelving, furniture, medical and domestic appliances and many other applications. Coil-anodised aluminium The surface of Novelis B73A is industrially pre-treated and coil anodised in a continuous
The term hard anodising is used to identify a very hard and compact aluminium oxide coating with greater thicknesses than decorative anodising. It is mainly used in precision mechanics on machined parts from solid, extruded, cast and rolled parts in order to increase corrosion resistance, hardness and wear
process, the aluminum oxide reacts with water to form aluminum hydroxide, which fills pores in the coating and seals the surface. The coefficient of thermal expansion of aluminum is about five times greater than that of aluminum oxide [3-5]. As a result, anodized coatings tend to craze or crack mainly because of the thermal
