2618 aluminum plate sheet detailed introduction:

2618 aluminum plate alloy is a cold-treated forging alloy with high strength, far better than mild steel. 2618 aluminum plate is one of the commercial 2618 strong alloys. Ordinary corrosion resistance, good mechanical properties and anode reaction. The small grains make the deep drilling performance better, the tool wear resistance is enhanced, and the thread rolling is more different.

2618 aluminum sheet physical and mechanical properties: elastic modulus E/Gpa: 71, hardness 150HB, density: 2810. Tensile strength 524Mpa, 0.2% yield strength 455Mpa: elongation rate 11%,

2618 aluminum plate sheet uses: aerospace industry, ultrasonic plastic welding molds, golf ball heads, shoe molds, blow molding (bottle) molds, paper plastic molds, foam molding molds, dewaxing molds, templates, fixtures, mechanical equipment, molds Processing.

Features of 2618 aluminum plate sheet

  • 1. High-strength heat-treatable alloy.
  • 2. Good usability.
  • 3. Good mechanical properties.
  • 4. Easy to process and good wear resistance.
  • 5. Good corrosion resistance and oxidation resistance.

Chemical composition of 2618 aluminum plate:

Zinc is the main alloying element of 2618 aluminum plate. Adding magnesium to the alloy containing 3%-7.5% zinc can form MgZn2 with significant strengthening effect, making the heat treatment effect of this alloy far better than that of aluminum-zinc binary alloy.

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.

After heat treatment, it can reach very high strength characteristics. 2618 aluminum plate materials are generally added with a small amount of copper, chromium and other alloys. Among the series, A2618-aluminum alloy is especially top-grade, and it is known as the excellent product of 2618 aluminum alloy. It has high strength and far better than any mild steel. To

2618 aluminum plate sheet has good strength, corrosion resistance and machinability among non-heat-treatable alloys. The surface is beautiful after anodization. Good arc welding performance. The main alloying element in 5083 alloy is magnesium, which has good corrosion resistance and weldability, and medium strength. Excellent corrosion resistance makes 2618 alloy widely used in maritime applications such as ships, automobiles, aircraft welding parts, subway light rail, pressure vessels that require strict fire protection (such as liquid tankers, refrigerated trucks, refrigerated containers), refrigeration devices, TV towers, Drilling equipment, transportation equipment, 2618 parts, armor, etc.
