Aluminium: Its Alloys and Extrusions
Aluminium metal is a soft, lightweight, durable, ductile and malleable. Pure aluminium has a low tensile strength, but when combined with other metals in accurate proportion it forms aluminium alloys with a marked improvement in its mechanical property. Majority of the materials (e.g. cans and aluminium foils) considered to be formed of aluminium are actually aluminium alloys. The components manufactured from aluminium by Aluminium extrusions manufacturer and its alloys are vital for wide array of industries like aerospace, transport, construction etc.
- The weight- It is approximately one-third of the steel. This property helps to extensively reduce the weight of the materials.
- Nonmagnetic- Thus, aluminium is used in the majority ships as it doesn’t affect compasses.
- Corrosion resistance- This property of aluminium has made it the preferred choice for engineering structures and automobile components
- There are a number of aluminium extrusion plants in India. However like the Indian aluminium industry, where the top few companies dominate the industry, the top players of the market also own the majority of the extrusion plants in India.
Aluminium Extrusion Process
Round ingots are preheated for the process of standard aluminium extrusions. An ingot is pressed at high pressure inside the steel die with the opening of required shapes. These extruded sections have many alternatives like large, small, hollow and solid to name a few.
- Relative movement of the ram and the extrusion, either Direct or indirect extrusion
- The type of load applied, either conventional (variable) or hydrostatic.
- Based on the position of press it can be vertical or horizontal
- Either hydraulic or mechanical depending on the type of drive
These aluminium extrusions are utilized in wide array of applications. They are extensively used in the world of sports for manufacturing of bats, tennis rackets, cycles etc.
Meticulous and splendid surface finish and complex cross-sections of finished parts are the major benefits of extrusion process.
