Product material description:
Zinc is the main alloying element in 7075. Adding magnesium to the alloy containing 3-7.5 zinc can form MgZn2 with significant strengthening effect, making the alloys heat treatment effect far better than aluminum-zinc binary alloy . Increasing the content of zinc and magnesium in the alloy will further improve the tensile strength, but its resistance to stress corrosion and spalling corrosion will decrease. After heat treatment, it can reach very high strength characteristics.
Note:
It is recommended to measure the length of your own screws before buying, and then check whether the information is consistent.
