5pcs MTB Bicycle Chainwheel Screws Plate Nail Cycling Chainring Wheel Bolt Alloy 7075 6.5mm Road Bike Disc Screws Crankset Parts

Description:

Explanation of terms: Zinc is the main alloying element in 7075. Adding magnesium to alloys containing 3% -7.5% zinc can form MgZn2 with a significant strengthening effect, making the heat treatment effect of the alloy far superior to aluminum-zinc binary alloys . Increasing the zinc and magnesium content in the alloy will further increase the tensile strength, but its ability to resist stress corrosion and spalling corrosion will be reduced. Withstand heat treatment, can achieve very high strength characteristics.

7075 ingredients are generally added with small amounts of copper, chromium and other alloys, among them, the 7075-T651 aluminum alloy is a top class known as the superior product for aluminum alloys. This alloy has good mechanical properties and anode reaction. Representative uses are aerospace, mold processing, mechanical equipment, tooling equipment, especially for manufacturing aircraft structures and other high-pressure structures that require high strength and strong corrosion resistance.
