Surface Treatment Of Metals , Black Anodizing Aluminum Alloy LED Part

Quick Detail:

1. 5-15 mm thick

2. Black color

3. Aluminum anodizing

Description:

The Anodizing process begins by immersing the work in a series of solutions where various operations are performed (described below). The solutions are held in open top tanks and the work passes through each unit. The work usually consists of distinct items that are placed on special racks and carried through the process in batches.

Applications:

Mac pro computer, iphone, ipod, MP3 and so on.

Specifications:

The most widely used anodizing specification is a U.S. military spec, MIL-A-8625, which defines three types of aluminium anodization. Type I is chromic acid anodization, Type II is sulfuric acid anodization, and Type III is sulfuric acid hardcoat anodization. Other anodizing specifications include more MIL-SPECs (e.g., MIL-A-63576), aerospace industry specs by organizations such as SAE, ASTM, and ISO (e.g., AMS 2469, AMS 2470, AMS 2471, AMS 2472, AMS 2482, ASTM B580, ASTM D3933, ISO 10074, and BS 5599), and corporation-specific specs (such as those of Boeing, Lockheed Martin, and other large contractors). AMS 2468 is obsolete. None of these specifications define a detailed process or chemistry, but rather a set of tests and quality assurance measures which the anodized product must meet. BS 1615 provides guidance in the selection of alloys for anodizing. For British defence work, a detailed chromic and sulfuric anodizing processes are described by STAN 03-24/3 and STAN 03-25/3 respectively.

Competitive Advantage:

1. Its hardness is high
2. Never lost color
3. Wear resistant
4. Non - conducting

The anodizing process

Anodizing (also spelled "anodising", particularly in the UK and Australia) is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts.
