Bismuth and Germanium Benefits
Metallic bismuth has strong diamagnetism and thermal interface materials has good thermal conductivity. Manufacturers widely use bismuth and Germanium as matrix materials. In addition, these metals can also be recycled and are very safe for the environment:
- Sustainability: Superior to the market product quality, Aster consistency is guaranteed;
- Customization: Offer various customization options (i.e., purity, size, shape, composition, packaging and logo);
- Higher standard: Meet the application requirements of low copper, low lead, low iron and other heavy metal contents.
- Vacuum operation: The production environment is pollution-free, and the surface is not oxidized.
Bismuth and Germanium Application
Bismuth Metal, also known as refined Bismuth, is often used to replace lead such as lead-free bullets, lead-free solder, and even medicines and cosmetics. In addition, it is also used in alloy smelting. Germanium is commonly used material for making optical lens and optical window in high efficiency infrared imaging system at 8-12 um.
Bismuth for Welding and Foundry
Mainly used in welding electrerials, radiation-proof clothes, chemical reaction, additives for producing steel and aluminum alloy and low melting solders.
Gallium Metal for GaAs and CIGS Thin-film Solar Cells
Widely used in GaN, GaAs concentrated solar cell and CIGS Thin-film solar cell, Nd-Fe-B advanced magnetic materials and Gallium based Low melting points alloy.
Indium for Encapsulating Semiconductor Materials
Mainly used for sealing materials, especially demountable cryogenic seals, also for low melting point metal alloys and semiconductor industry.
Gallium Alloy for Thermal Interface Cooling Layer
Ga alloy fluid or paste is penetrated into the gap between CPU and heat dissipation module as filling, rapid conduction of heat to the cooling module

What Our Old Customers Say
For the 3rd consecutive year, we’ve procured raw materials from Aster, and every shipment we’ve obtained has performed impeccably without fail. Thank you, our preferred supplier for MTB.
All items arrived quickly and in excellent condition, lower test value than standard for impurities. The surface is clean, uniform. Materials came clearly labeled and sealed in separate vacuum bag.
They are always delightful to work with, very friendly and professional. We are a small scale buyer and have the Bismuth shipped to Seoul. We have sources in Euro who take longer to deliver than Hunan Aster. It’s hard to overstate how much premium product, and that is what we get every time.
As always prompt and precise delivery. The online images and the delivered material agree very well. Their delivery is fast and packaged with care, so affordable! (for now) I am grateful to work with Aster team.
