7010 Alloy Uses in Industries

  • Aerospace industry
  • Automotive industry
  • Marine industry
  • Defense industry

7010 Alloy Corrosion Resistance

Aluminium 7010 has excellent corrosion resistance properties due to its high chromium content. This provides protection against oxidation and prevents rust from forming on the surface of the alloy. Additionally, it has good weldability making it suitable for welding applications where a high degree of corrosion resistance is required.

7010 Alloy Heat Resistance

Aluminum 7010 has very good thermal conductivity, making it ideal for use in applications that require efficient heat transfer, such as radiators or heat exchangers. Additionally, it has a high melting point, allowing it to withstand temperatures up to 650°C (1,202°F). This makes it an excellent choice for parts that operate at elevated temperatures, such as turbines or exhaust systems.

7010 Alloy Heat Treatment

Aluminium 7010 can be heat treated to increase its strength and improve its wear resistance properties. The most common heat treatment process involves heating the material at around 600°C (1,112°F) followed by quenching in water or air cooling until room temperature is reached before ageing at 190°C (374°F) for two hours. This process will result in improved mechanical properties without sacrificing any of its corrosion resistance abilities.

7010 Alloy Machining

Aluminium 7010 can be machined using conventional tools but should be done with proper coolant lubricants to prevent overheating during operation, which can lead to tool wear or workpiece damage. Additionally, due to its relatively low melting point compared to other metals, it should be machined at low speeds and pressures when possible to reduce friction between tool and workpiece which could generate excessive heat buildup during machining operations resulting in poor surface finish or even worse – tool breakage!

7010 Alloy Welding

Aluminum 7010 can also be welded using conventional welding techniques such as TIG welding or MIG welding with filler materials like ER70S2 or ER70S6 wire rods, depending on the application requirements. However, proper shielding gas must be used when welding this alloy since it tends to form oxides quickly when exposed to oxygen which could lead to porosity issues if not addressed properly during welding operations!


In conclusion, aluminium 7010 is an extremely versatile material with many desirable properties, including excellent corrosion resistance, good machinability, good weldability and thermal conductivity, and the ability to withstand temperatures up to 650°C (1,202°F). Proper heat treating will further enhance these characteristics making aluminium7010 an excellent choice for a variety of applications ranging from aerospace components to automotive parts and structural applications requiring superior strength and durability! With a proper selection of materials along with proper fabrication techniques like machining & welding, this material can provide maximum performance benefits while keeping costs low!
