Aluminum
alloys bar 7050 are utilizing aerospace manufacturing technology of
multi stage purification ,grading homogenaiztion,special fine
crystallization and SPC control in the manufacturing process, which are
widely applied in automotive,ralil,electronice,weapons and
equipment,aviation industries
Commonly used in aircraft structural parts for plate extrusions, free forgings and die forgings. The alloy requirements for the manufacture of such parts are: resistance to exfoliation corrosion and stress corrosion cracking, as well as strong fracture toughness and fatigue resistance.

General Characteristics of Styrene Butadiene rubber SBR OÂ rings
SBR probably is better known under its old names Buna S and GRS (government rubber styrene.) SBR was first produced under government control between 1930 and 1950 as a replacement for natural rubber. The basic monomers are butadiene and styrene, with styrene content approximately 23.5%. About one third of the world output of SBR is used in tire production. SBR is mostly used in seals for non-mineral oil based brake fluid applications.
Temperature Properties of Styrene Butadiene rubber SBR OÂ rings
Heat    Heat Resistance    Up to approximately 225°F (107°C).
Cold    Cold Flexibility    Down to approximately -70°F (-57°C).
Compatibility of Styrene Butadiene rubber SBR OÂ rings
Chemical Resistance    Chemical Resistance   Â
Water, alcohol, glycol, and certain ketones (acetone)
Non-mineral oil based brake fluid
Silicone oil and grease
Diluted water solutions, weak acids
Not compatible    NOT compatible   Â
