7075 aluminum alloy Material with cnc milling in cnc factory

Basic introduction

7075 aluminum alloy is a cold treatmentForgingAlloy, high strength, far better thanSoftsteel. . 7075 is one of the most powerful commercial alloys. 7075 aluminum alloy has a tight structure and strong corrosion resistance, and is the best for aviation and marine plates  with cnc milling in cnc factory. Ordinary corrosion resistance, good mechanical properties andAnodic reactions. Fine grains make deep drilling performance better and tool wear resistance enhanced.

Mechanical properties

Tensile strength σb (MPa):≥560

Elongation stress σp0.2 (MPa):≥495

Elongation δ5 (%):≥6

Note: Mechanical properties of seamless pipes

Sample size: diameter ≥12.5

Heat treatment

The forming performance is relatively good in the state, annealing and new quenching state, and the heat treatment strengthening effect is significant, but the heat treatment process requires strict requirements. It has poor corrosion resistance, but it can be effectively protected by cladding with pure aluminum; cracks are easy to produce when welding, but it can be welded or riveted using a special process
