7075 aluminum plate is a cold-treated forging alloy with common corrosion resistance, good mechanical properties and high anode reaction strength, far better than mild steel. 7075 is one of the most powerful alloys for commercial use. Common corrosion resistance, good mechanical properties and anode reaction. The fine grain size makes the deep drilling performance better, the tool wear resistance is enhanced, and the thread rolling is more different from the weight. The 7075 aluminum plate is used in the aircraft industry and is still widely used in the aviation industry for ultra-high-strength deformed aluminum alloys. It is characterized by good plasticity after solution treatment, particularly good heat treatment strengthening effect, high strength at higher temperature, and particularly good low temperature strength; poor weldability; stress corrosion cracking tendency; Other protection treatments are used. Two-stage aging improves the ability of the alloy to resist stress corrosion cracking. The plasticity in the annealed and quenched state is slightly lower, the static fatigue of the sheet. The gap is sensitive, and the stress corrosion performance is better than 7A04. It is known as the most excellent product in aluminum alloy, and its strength is much higher than that of mild steel. This alloy has good mechanical properties and anodic reaction and is a typical aerospace aluminum. It is used to manufacture aircraft structures and other high-stress structural parts that require high strength and high corrosion resistance, such as aircraft upper and lower wing panels, purlins, and partitions. After solution treatment, the plasticity is good, the heat treatment strengthening effect is particularly good, the strength is below 150 ° C, and the low temperature strength is particularly good, the welding performance is poor, the stress corrosion cracking tendency is tendency, and the double-stage aging can improve the anti-performance. Wuxi Hanshin Metallurgy offers. Aluminum alloy with zinc as the main alloying element, but sometimes a small amount of magnesium or copper is added. Among them, super-hard aluminum alloy is composed of zinc, lead, magnesium and copper alloy. It is close to the hardness of steel. It can be heat-treated and strengthened. It is a high-strength heat-treatable alloy with ordinary corrosion resistance. Good mechanical properties improve the zinc and magnesium content in the alloy after heat treatment. The tensile strength will be further improved, but its resistance to stress corrosion and flaking corrosion will decrease. Can reach very high strength characteristics. 7075 materials are generally added with a small amount of copper, chromium and other alloys. Among them, A7075-aluminum alloy is especially top grade. It is known as the most excellent product in aluminum alloy, with high strength and far better than any mild steel.

Downhole tools for oil rigs include: stabilizers, scrapers, centralizers, etc.
The replaceable sleeve stabilizer are available with two-piece and three-piece construction. The three-piece construction stabilizer is made of a body and a centralizing body(refer to sleeve replaceable). The advantage is that the sleeve can be changed quickly and easily after sleeve hardfacing is worn-out. This kind of stabilizer is especially suitable for working in directional well .
