GB 3190–82 is the standard for chemical compositional requirements for aluminum and aluminum alloy processing products. It sets forth the minimum and maximum allowable nitrogen, carbon, silicon, manganese, magnesium, zinc, aluminum, phosphorus and other key elements, as well as their impacts on product performance and quality.

To understand the standards and requirements of GB 3190–82, it is important to understand the related terminology used in the document.

Nitrogen: A non-metallic element usually found in aluminium and other alloys. It has an important effect on the mechanical strength and corrosion resistance of the material.

Carbon: Carbon is a major constituent of aluminium and other alloys. It can also act as an alloying element, improving the strength of the alloy due to its relationship with other elements.

Silicon: A metalloid element commonly used in aluminium and other alloys. It is highly attractive to oxygen, forming a protective oxide layer that helps the material withstand corrosion.

Manganese: An element which can be used to improve the strength, hardness, and wear resistance of aluminium and other alloys.

Magnesium: A metallic element which can be used in aluminium and other alloys to achieve lighter weights, enhanced mechanical strength, improved machinability and improved formability.

Zinc: A metallic element traditionally used in aluminium and other alloys to improve its corrosion resistance.

Aluminium: Aluminium is the major element in aluminium and other alloys. It is light in weight, strong, and corrosion resistant.

Phosphorus: An element which can be used to increase the strength, rigidity and corrosion resistance of aluminium and other alloys.

GB 3190–82 also sets forth requirements for the production and testing of the chemical composition of aluminium and other alloy products. It states that sampling should be performed at the time of receiving raw materials or products from suppliers or production, and sets forth the methods for sampling and testing.

Finally, the standard outlines the categories of defects in products and makes provisions for their inspection.

By understanding and abiding by the requirements of GB 3190–82, producers of aluminium and other alloy products can ensure that the product meets the desired performance and quality standards. Adherence to this standard can help protect the safety, performance and quality of the products, as well as help reduce costs and improve customer satisfaction.
