Anodized Aluminum Machined Parts , Black Anodized Aluminum OEM
Our company supply various aluminum alloy profile, machined parts
and precision machined parts.
First according to section design of product to make mould , and
using extrusion machine to extrude heating casting round bar from
Commonly grade 6063alloy,in the extrusion also use a air cooling
quenching process and subsequent artificial aging process to
complete heat treatment strengthen. Different grade of heat
treatment strengthen alloy, the different heat treatment system.
Aluminum alloy profiles of extrusion, the surface corrosion
resistance is not strong, it must process the surface by anodized
in order to increase aluminium corrosion resistance, abrasion
resistance and the appearance.
6061: need to have a certain strength, weldability and high
resistance in various industrial structural, such as manufacturing
trucks, tower building, ship, tram, furniture, machinery parts,
precision machined parts with tube, bar, profiles and plate.
6063: industry profiles, building profiles, irrigation pipe and
extruded material for vehicles, rack, furniture, barrier etc.
7075: used in the manufacture of aircraft structure and other
requirements of high strength , high stress structure of strong
corrosion resistance, mold making.
According to drawings to process
1) Surface preparation: We use chemistry and physical method to
clean the surface of profile, bare pure matrix, in order to get
complete and compact artificial oxide film. It can also obtain
mirror surface or matt surface by machinery.
2) Anodize: The surface pretreatment of profiles, in a certain
process condition, the matrix surface anodize, and generate a AL203
film of dense
, porous and strong adsorption.
3) Hole sealing: sealing pore of porous oxide film after anodizing,
make oxide film strengthen Pollution prevention, against corrosion
and abrasion resistance. Oxide film is clear and colorless, use
strong adsorption of oxide film before hole sealing adsorb and
deposit some metal salt within film hole, can make profiles appear
many colors other than natural color(silver and white color), such
as : black, bronze, golden yellow and stainless steel color etc.
