7075 Aluminum Alloy CNC Machined Parts Fasteners
7075 Aluminum alloy CNC machined Fasteners for fixed connectors for outdoor fitness equipment
Scope
Aluminium alloy 7075 is a medium strength alloy commonly referred to as an architectural alloy.It is normally used in intricate extrusions.It has a good surface finish, high corrosion resistance, is suited to welding and can be easily anodised.The T6 and T651 tempers have fair machinability, resistance welding and corrosion resistance ratings. This alloy is heavily utilised by the aircraft and ordnance industries because of its superior strength.
Application
This material is used for architectural applications, shop fittings, irrigation tubing, balustrading, window frames,3C heat dissipation, machinery, automobile, aviation, military, outdoor fitness equipment, outdoor fitness equipment. extrusions and doors.
Supplied Forms
1 Extrusions
2 Tube
