High toughness, no deformation after processing,pact material without defects and easy polishing, easy color film, good oxidation effect, etc. 6061 t6511 Aluminum anodic oxidation. 6061-T651 aluminum alloy has friendly surface treatment and anodizing characteristics, especially 6061-T651 aluminum alloy has a good response to hard oxidation.Aluminum 3105 (UNS A93105) in Coil Form. Description. Aluminum alloy 3105 is essentially a 98% aluminum ease strength over that of alloy 1100 and 3003. It is not hardenable by heat treatment and it has good corrosion resistance, formability and weldability.Introduction to 4 x 12 aluminum sheet. 4 x 12 aluminum sheet has good corrosion resistance, weldability and easy processing and forming. In foreign countries, 4’’ x 12’’ alloy aluminum plates with different heat treatment conditions are the main materials used in the automobile manufacturing industry (car doors, molds, seals) and canning industries.2. Applications of 3105 Aluminium Coils . 3105 Aluminium Coils are of high plasti, hard in corrosion, good at electrical and thermal conductivity. 3105 Aluminium Coils are widely used in air conditioner, aluminiumposite panel, aluminium ceiling, road traffic sign, decoration, cover material, piping, refrigeration, automobile, etc. 3.
