About Silicon Aluminum Alloy Si-Al Powder:
High-silicon aluminum alloy powder is a binary alloy composed of silicon and aluminum and is metal-based thermal management material. The high-silicon aluminum alloy material can maintain the excellent performance of silicon and aluminum, and the content of silicon and aluminum is quite rich. The preparation technology of silicon powder is mature and the cost is low. At the same time, this material does not pollute the environment and is harmless to the human body. Why is Silicon added to Aluminium?
When it is added to aluminum, the silicon makes the metal alloy more fluid without breaking the metal down at high temperatures. The silicon actually lowers the aluminum’s melting point. The aluminum will not experience hot tearing as there is no brittleness.
The density of high-silicon aluminum alloy is between 2.4~2.7 g/cm³, and the coefficient of thermal expansion (CTE) is between 7-20ppm/℃. Increasing the silicon content can significantly reduce the density and thermal expansion coefficient of the alloy material. At the same time, the high-silicon aluminum alloy also has good thermal conductivity, high specific strength and stiffness, good plating performance with gold, silver, copper, nickel, weldable with the substrate, easy precision machining and other superior performance, is an Electronic packaging material with broad application prospects, especially in high-tech fields such as aerospace, space technology, and portable electronic devices. Tqhp is a trusted global Silicon Aluminum Alloy Si-Al Powder supplier. Feel free to send an inquiry about the latest price of Silicon Aluminum Alloy at any time.

How is Silicon Aluminum Alloy Si-Al Powder Produced?
Preparation method of silicon and aluminum alloy:
(1) no pressure infiltration method
In the role of carbon steel permeability aid in the air, make the aluminum alloy melt into the silicon particle prefabricated parts, so as to prepare a composite material method;
(2) pressure infiltration method
By applying an external force, liquid aluminum metal penetrates into the preform of silicon particles to promote the penetration, wetting and recombination of silicon particles and liquid aluminum metal. The usual steps are to prepare the prefabricated silicon particle reinforcements and then cast the permeable composites.
(3) vacuum hot pressing method
A sintering process in which pressure forming and pressure sintering is carried out simultaneously under vacuum conditions;
(4) powder metallurgy method
A method of making a certain proportion of aluminum powder, silicon powder and binder by dry pressing, injection and other methods to make powder mixing molding, and sintering in a protective atmosphere, so as to obtain a dense material;
(5) rapid solidification method
Also known as rapid solidification, the solidification degree and solidification speed can be increased by increasing the solidification cooling rate, so as to achieve the purpose of refining the microstructure of the alloy.

Application of Silicon Aluminum Alloy Si-Al Powder:
1) High-power integrated circuit packaging: high-silicon aluminum alloy provides effective heat dissipation;
2) Carrier: It can be used as a local heat sink to make the components more closely arranged;
3) Optical frame: high-silicon aluminum alloy provides low thermal expansion coefficient, high rigidity and machinability;
4) Heat sink parts: high silicon aluminum alloy provides effective heat dissipation and structural support.
Application of Silicon Aluminum Alloy Si-Al Powder in auto parts:
High-silicon aluminum alloy material (with a silicon content of 20%-35%) has excellent tribological properties and can be used as an advanced lightweight wear-resistant material in various transportation vehicles and various types of power machinery, machine tools, special fasteners And tools have been widely used.
High-silicon aluminum alloy has a series of advantages such as small specific weight, lightweight, good thermal conductivity, low thermal expansion coefficient, volume stability, good wear resistance, good corrosion resistance, etc., and is widely used as cylinder sleeves, pistons, rotors of automobile engines, Brake discs and other materials.

Storage Condition of Silicon Aluminum Alloy Si-Al Powder:
The damp reunion will affect Si-Al powder dispersion performance and using effects, therefore, silicon aluminum alloy powder should be sealed in vacuum packing and stored in cool and dry room, the silicon aluminum alloy can not be exposure to air. In addition, the silicon aluminum alloy powder should be avoided under stress.

Packing & Shipping of Silicon Aluminum Alloy Si-Al Powder:
We have many different kinds of packing which depend on the silicon aluminum alloy Si-Al powder quantity.
Silicon aluminum alloy Si-Al powder packing: vacuum packing, 100g, 500g or 1kg/bag, 25kg/barrel, or as your request.

About Metal Alloy High Purity Titanium Sputtering Target:

Standard:
ASTM B265, ASME SB265, ASTM F67, ASTM F136, AMS 4902, AMS 4911

Properties:
Titanium sputtering target is made of titanium metal, which is recognized for its high strength-to-weight ratio. It is a strong metal with low density that is quite ductile (especially in an oxygen-free environment), lustrous, and metallic-white in color. The relatively high melting point (more than 1,650 °C or 3,000 °F) makes it useful as a refractory metal. It is paramagnetic and has fairly low electrical and thermal conductivity.

Application:
mainly used for integrated circuit, DRAMS and flat panel display application.
