7075 Aluminum Coil

7075 Aluminum Coil is a cold-treated forging alloy with high strength, far better than mild steel.

Description

7075 Aluminum Coil

7075 Aluminum Coil is a cold-treated forging alloy with high strength, far better than mild steel. 7075 is one of the most powerful alloys commercially available. The 7075 aluminum alloy has a compact structure and strong corrosion resistance, which is best for aviation and marine plates. General corrosion resistance, good mechanical properties and anode reaction. The finer grains make the deep drilling performance better, and the tool wear resistance is enhanced.

Features: Compact structure, strong corrosion resistance

Introduction

7075 Aluminum Coil is a cold-treated forging alloy with high strength, far better than mild steel. 7075 is one of the most powerful alloys commercially available. General corrosion resistance, good mechanical properties and anode reaction. The finer grains make the deep drilling performance better, the tool wear resistance is enhanced, and the thread rolling is more distinctive. Zinc is the main alloying element in 7075. Adding magnesium to an alloy containing 3%-7.5% zinc can form MgZn2 with a significant strengthening effect, making the alloy's heat treatment effect far better than aluminum-zinc binary alloys. 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 accordingly. After heat treatment, very high strength characteristics can be achieved. The 7075 material is generally added with a small amount of copper, chromium and other alloys. Among the series, the 7075-T651 aluminum alloy is especially the top grade. It is known as the most excellent product in the aluminum alloy. It has high strength and far better than any mild steel. This alloy also has good mechanical properties and anodic reaction. Representative applications include aerospace, mold processing, mechanical equipment, tooling and fixtures, especially for the manufacture of aircraft structures and other high-stress structures that require high strength and strong corrosion resistance.
