Aluminum Alloy Girder

Aluminum alloy girder is an industrial building material. It is used in various industries based on different raw materials and can be divided into two categories: unpainted products and painted products according to surface treatment methods. The applicable industries include aircraft structures, rivets, missile components, truck hubs, packaging and thermal insulation aluminum foil, heat exchangers, bulkheads, ribs, spars, etc.

Aluminum Alloy Plates

1. Product Selection Guide & Classification

Classified by coating process: spray-coated panels and pre-rolled coated panels.

Classified by paint type: polyester, polyurethane, polyamide, modified silicone, fluorocarbon, etc.

2. Specifications of Aluminum Alloy Girders

Single-layer aluminum plates can be pure aluminum plates, manganese alloy aluminum plates, and magnesium alloy aluminum plates.

Fluorocarbon aluminum plates include two types: fluorocarbon-sprayed panels and fluorocarbon pre-rolled coated aluminum plates.

Plates with a thickness of ≥ 2.0mm are used to process parts and components that require good formability and high corrosion resistance but not high strength. Examples include food industry equipment and storage containers, sheet metal workpieces, deep-drawn or spun concave vessels, welded parts, heat exchangers, printed circuit boards, nameplates, and reflective devices. They are also used to process parts and components that require good formability, high corrosion resistance, and excellent weldability.

With the rapid development of science and technology as well as industrial economy in recent years, the demand for aluminum alloy welded structural parts has increased significantly, leading to in-depth research on the weldability of aluminum alloys. The wide application of aluminum alloys has promoted the development of aluminum alloy welding technology, and the development of welding technology has in turn expanded the application fields of aluminum alloys. Thus, aluminum alloy welding technology has become one of the research hotspots. Aluminum alloys are easy to process and can be made into various profiles and plates. They have good corrosion resistance, but pure aluminum has very low strength.

Through long-term production practice and scientific experiments, people have gradually strengthened aluminum by adding alloying elements and using heat treatment, resulting in a series of aluminum alloys. Alloys formed by adding certain elements not only retain the advantages of pure aluminum such as light weight but also have higher strength, surpassing many alloy steels. They have become ideal structural materials and are widely used in machinery manufacturing, transportation machinery, power machinery, aerospace industry, etc. Aircraft fuselages, skins, compressors, etc., are often made of aluminum alloys to reduce their own weight. Using aluminum alloys instead of steel plates for welding can reduce the structural weight by more than 50%.
