Choosing the Right Low Melting Point Alloys for your Small Business

Manufacturing companies around the world depend on high-quality materials to create a broad range of equipment, products, and parts for small business. During the assembly procedure, various materials might need to be fused for a tight seal, molded to form the designed design or bent in the right direction without crumbling. Low melting point alloys features a composition that lets the metal change into a semi-liquid or liquid form at lower temperature and re-solidify later.   These alloys are ideal since they enable various parts to be fused or cast at lowest temperatures.

Choosing the best low melting point alloy for your business is important. It ensures that the part that is fused, cast, or twisted maintains its durability and strength for the required application. Small business owners need to have extensive knowledge about different types of low melting alloys and their features when they solidify. This will help them choose the right alloy for their application needs.

Types of low melting point alloys and their features

There are numerous types of low melting point alloys in the market. However, some types are limited in their use, depending on their toxicity, reactive, and brittleness qualities. These elements include tin, zinc, gallium, bismuth, antimony, mercury, thallium, lead, and cadmium. Most of these minerals might be additives used during the creation of low melting point alloys. Let’s look at some of the common alloys.

  • Tin-based

Pewter is the mostly used tin-based low melting point alloy. It comprises a composition base that has almost 50% tin constituent in the alloy. Many manufacturers or pewter suppliers prefer tin because of their malleability when they want a material that has ductile features. The metal can be precast and reshaped without becoming brittle.

  • Bismuth-based

Bismuth alloys tend to have a composition that less ductile than tin since it easily becomes brittle. Manufacturers choose bismuth because of its expansion traits when melting and then solidifies since it can expand to a maximum of 3.3 %. This alloy is cheap compared to other low melting alloys and it’s not lethal since it is utilization in the application where drinking water is available.

  • Indium-based

Indium low melting point alloys are utilized when bonding onto glass, ceramic, and gold surface. The alloy can as well weld onto its surface, with the capability to wet both metallic and non-metallic surface. When searching for a ductile substance that provides a great fatigue resistance and a range of melting points, manufacturing companies can choose indium alloys.

  • Gallium-based

Since it has a very low melting point, gallium alloys can melt when held on an individual’s hand. The alloy transforms into a liquid at normal temperatures. For this reason, it is used for thermal management applications. Gallium alloys can as well be used to wet on metallic and non-metallic surfaces like porcelain and glass.
