Heatsink

A heatsink is a metallic device that absorbs thermal energy, or heat, from another object using thermal compounds known as
thermally conductive materials. Heat is absorbed from the object at a relatively high temperature and transferred to the heatsink,
which has a larger heat capacity. Extruded heatsinks are a thermal energy solution for both low and high volumes and are used in
refrigeration, heat engines, cooling medical devices, lasers , and CPUs.

 

 

Aluminum Shapes

Aluminum shapes are linear aluminum products highly valued in a wide spectrum of structural applications due to aluminum's high
strength-to-weight ratio and the cost effectiveness of the metal extrusion process. Aluminum is one of the most recent metals to
be used in industrial manufacturing processes with just over a hundred years of usage in industrial and commercial applications.
However, aluminum shapes have a far longer service life than most metal extruded shapes and are therefore embraced. Standard
aluminum shapes include beams, trim caps, rods, angles, bars and channels, all of which are available in a wide range of
configurations and sizes.

 

 

 

 

 

Properties of Aluminum

High Strength-to-Weight Ratio: Aluminum is widely popular due to its light weight and high strength. Its density is about one-third that of steel. Depending on the grade, aluminum alloys are stronger than steel by up to a factor of five. Because of this property, aluminum is widely used in aerospace and automotive applications.

Corrosion Resistance: Aluminum has an inherently high corrosion resistance compared to most metals. This is attributed to its tendency to form compact layers of oxides on its surface. This makes aluminum suitable for outdoor applications after a coating has been added.Electrical Conductivity: The electrical conductivity of aluminum is around 61% that of copper. It is preferred over copper for certain applications due to its lower density and cheaper cost. An application that takes advantage of these properties is low-cost power transmission lines.Thermal Conductivity: Aluminum conducts heat twice that of brass and four times that of steel. This makes aluminum extensively used in heat sink applications in electronics and electrical components.

Ductility and Workability: Aluminum can be easily formed even at room temperatures. Aside from extrusion, aluminum can be formed by rolling, drawing, stamping, and forging.
Low-temperature Toughness: In contrast with steel, aluminum retains its toughness at low temperatures. Low temperatures typically make metals fail under brittle fractures. The mechanical properties of aluminum are almost constant across all temperatures.
Resilience and Impact Strength: Aluminum has high resilience and impact strength because of its natural toughness. Aluminum parts can absorb sudden forces or shocks and can elastically flex from dynamic loads.

Non-magnetic: Unlike steel, aluminum is not ferromagnetic but paramagnetic. This means it does not acquire a magnetic charge when subjected to strong magnetic fields. This makes aluminum suitable for electronic and electrical enclosures and parts that emit high electromagnetic fields. Moreover, along with its electrical conductivity, aluminum can be used to create electromagnetic field shields.
Reflectance: Aluminum has the highest reflectance of any metal in the 200 to 400 nm range, much better than gold and silver.Aluminum film coating is commonly applied on the glass to make mirrors instead of silver. Depending on its finish, aluminum can reflect about 90% of light across the visible spectrum wavelengths.

Recyclability: Aluminum is easily recycled without any loss of desirable properties. The energy required to recycle aluminum is only about 5% of the energy consumed to produce a virgin product.
