Aluminum extrusion: Solid aluminum bars are heated to a softened state and then extruded through a die under high pressure in an extrusion press, without melting the metal. Extrusion involves heating and pressurizing solid aluminum rods and then shaping them through a die. It is suitable for producing profiles with a consistent cross-section (such as door and window frames profile). It offers high tensile strength (due to significant processing deformation) and is suitable fo

Introduction to Extrusion Dies The design and manufacturing of extrusion dies involve numerous steps, including material selection, design, manufacturing, and die repair. Their cost accounts for approximately 35% of the total cost of profile extrusion production. In profile processing, there are generally two main extrusion methods: sprue-combination die extrusion and pin-punch extrusion. The former is simpler to process and has lower costs, while the latter is more expensive

Global Leadership: Aluminum profile at the Center of Growth In 2024, global primary aluminum output reached 72.86 million tons, while China’s aluminum profile production alone exceeded 21.55 million tons, accounting for nearly half of the world’s output. Aluminum profiles now represent over 43% of all aluminum processed products in China, confirming their dominant role. Despite its massive scale, the industry remains “large but not strong”, with relatively low product value a

Aluminium Profile in Transportation Aluminium profiles have become one of the most essential structural materials in today’s transportation industry. Thanks to their lightweight nature , aluminium components help reduce overall vehicle mass, improve energy efficiency, and extend driving range—whether in automobiles, railway systems, ships, or aerospace applications. Compared with traditional steel, aluminium offers an excellent strength-to-weight ratio , allowing engineers to

Aluminium profiles play a critical role in the structural design of modern UAVs (Unmanned Aerial Vehicles), providing the ideal balance between strength, light weight, and high precision. Thanks to their excellent strength-to-weight ratio, aluminium alloys such as 6061-T6 and 7075-T6 are widely used to build UAV frames, arms, landing gears, and mounting brackets. These profiles help reduce overall aircraft weight while maintaining the rigidity required for stable flight and h

Annealing of Aluminum Profiles Annealing is a heat-treatment process used to modify the internal structure of aluminum profiles by controlled heating, holding, and cooling. Through this process, the alloy’s microstructure becomes more uniform, allowing the material to achieve improved mechanical properties and better processing performance. The primary purpose of annealing aluminum is to eliminate internal stresses  generated during extrusion, machining, or cold deformation.

Aluminum extrusion is a manufacturing process that transforms a solid aluminum billet into a continuous profile with a specific cross-section. By pushing heated aluminum through a precision-designed die, manufacturers can create strong, lightweight, and highly customizable shapes used in construction, automotive, electronics, and countless industrial applications. 1. From Billet to Extrudate The process begins with a cylindrical aluminum billet, usually from the 6xxx series—a

The thermal performance of aluminum and its heatsinks depends on two core aspects: alloy composition  and heat treatment condition . Understanding how these factors influence heat conduction allows engineers to design heatsinks with higher efficiency and stability. 1. Alloying Elements and Their Impact on Aluminum’s Thermal Transfer For aluminum materials, especially heatsinks in electronics, alloying elements are the most critical factor affecting thermal conductivity . Pure

3xxx series aluminum alloys are mainly aluminum–manganese (Al–Mn) based materials, with Mn  as the principal alloying element. In alloys such as 3003 , manganese is typically added in the range of 1.0–1.6% . Manganese improves the mechanical strength and corrosion resistance of the alloy by forming stable intermetallic compounds like Al₆Mn , which exhibit excellent thermal stability. However, excessive Mn content can reduce castability, while insufficient Mn lowers the mechan
