7075 aluminum alloy is a cold-processed forged alloy with high strength, meget bedre end blødt stål. 7075 er en af de stærkeste legeringer, der er kommercielt tilgængelige. Generel korrosionsbestandighed, gode mekaniske egenskaber og anodisk reaktion. Fine grains allow for better deep drilling performance, enhanced tool wear resistance and distinctive thread rolling.
7050 is a high-strength heat-treatable alloy with extremely high strength and resistance to spalling corrosion and stress corrosion cracking. Commonly used in aircraft structural parts for medium and thick plates, extruded parts, free forging parts and die forging parts.
7075 aluminiumplade is an Al-Zn-Mg-Cu series superhard aluminum. 7075 alloy is an ultra-high strength deformed aluminum alloy widely used in the aviation industry. It is characterized by good plasticity after solution treatment and particularly good heat treatment strengthening effect. It has high strength below 150℃, and has particularly good low-temperature strength. The plasticity in the annealed and freshly quenched states is slightly lower than that of 2A12 in the same state. It is slightly better than 7A04. The plate is static fatigue and notch sensitive, and has excellent stress corrosion properties. Among 7A04, 7075T651 is particularly top-grade and is known as the best product among aluminum alloys. It has high strength and is far better than mild steel. This alloy has good mechanical properties and anodic reaction, and is a typical aviation aluminum.
Det 7075 varieties are divided into plates, thick plates, stretched tubes, extruded tubes, stænger, former, rows, wire rods, rolled or cold-processed bars, and cold-processed wire rods. The states include O state, T6 state, T651 state, T6511 state, T73 state, T7351 state, T7651 state, T76511 state, and H13 state.
Typiske anvendelser af 7075 aluminum are aerospace industry, blow molding (flaske) forme, ultrasonic plastic welding molds, golf ball heads, shoe molds, paper molds, foam molding molds, dewaxing molds, skabeloner, inventar, mekanisk udstyr, mold processing and other corrosion-resistant high-stress structural parts
Zinc is the main alloy element in 7075. Adding magnesium to an alloy containing 3%-7.5% zinc can form MgZn2 with significant strengthening effect, making the alloy’s heat treatment effect far better than that of aluminum-zinc binary alloys.
Aluminium Sheet / Plade 7075-T6/T651 bruges normalt til rumfart, militær, og bilapplikationer. 7075 aluminium er det stærkeste aluminium, med styrken af mange stål, Mens han bevarer aluminiums lette kvaliteter og korrosionsbestandighed.

Aluminium 7075 er medlem af 7000 serie, som har zink som sin vigtigste legeringskomponent og er kendt for sin ekstraordinære høje styrke. Tempereringsbehandling kan så yderligere forbedre dens høje mekaniske styrke. Denne egenskab gør legering 7075 meget populær i luftfarts- og forsvarsindustrien.
Dens styrke kan sammenlignes med mange typer stål, men den har en meget lavere tæthed. Legeringen er en fremragende erstatning for stål i højspændingsapplikationer. Den udmærker sig også ved at modstå træthedsstress, gør den meget pålidelig, en kvalitet, der er meget efterspurgt i de ovenfor nævnte brancher.
Legering 7075 tilbyder kun gennemsnitlig korrosionsbestandighed, et resultat af den lille mængde kobber, der indgår i dets kemiske sammensætning. Den har også rimelig bearbejdelighed og dårlig formning og svejsbarhed. En anden ulempe ved denne legering er, at den har en forholdsvis høj pris i forhold til andre aluminiumslegeringer på grund af dens exceptionelt høje styrke.
