Aluminium Heat Sink is the most widely used product in thermal solutions. Aluminium is the second most widely used metal in the world after iron. After oxygen and silicon, aluminum is the most common element in the earth's crust.
Features that make aluminum heat sinks popular include:
Good thermal and electrical conductivity
Low density, density ~ 2,700 kg/m3
High strength between 70 and 700 MPa
easy to process
Excellent corrosion resistance
Non-magnetic, avoid magnetic field interference
easy to recycle
Compared with other metals, aluminum has a relatively large coefficient of linear expansion. The ductility of aluminum is critical for extrusion processes, bending and other formed products.
Aluminum heat sinks are excellent conductors of heat.
