There is a wide range of low melting alloys available. Yet some are restricted in their use based on their brittleness, toxicity, and reactive qualities. Some of these elements are bismuth, gallium, tin, indium, zinc, cadmium, tellurium, antimony, thallium, mercury, and lead. Many of these minerals may also be additives placed during the formation of the low melting alloys. ;

Bismuth Alloys

Bismuth-based: Bismuth alloys will have a composition that is less of a ductile characteristic than tin, as it can become brittle. Manufacturers use bismuth due to its expansion qualities when it melts and then solidifies as it can expand to up to 3.3%. The more bismuth is in an alloy, the more it expands. It is less expensive than other alloys that are featured and the least toxic as it can be used in applications where there is drinking water present. ;

Bismuth compounds account for about half the production of bismuth. They are used in cosmetics; pigments; and a few pharmaceuticals, notably bismuth subsalicylate, used to treat diarrhea. Bismuth's unusual propensity to expand as it solidifies is responsible for some of its uses, such as in the casting of printing type. Bismuth has unusually low toxicity for heavy metals. As the toxicity of lead has become more apparent in recent years, there is increasing use of bismuth alloys (presently about a third of bismuth production) as a replacement for lead.

5 Types Of Indium Alloys You May Want To Know

A Brief Introduction To The Indium Alloy

Indium alloy is generally divided into binary alloys, ternary alloys, and multi-component alloys.

Generally, the melting temperature of indium alloy mainly composed of indium is relatively low, which is mainly used as some low melting point alloys or solders.

Lead-tin

Lead-tin alloys containing up to 98 percent by weight in are used as soldiers. The strengths of these alloys increase with higher tin content, while the melting point is lowered to a minimum of 183 °C (361 °F) with a lead content of 38 percent. A half-lead–half-tin alloy is the most common general-purpose solder. Considerably lower tin contents, from around 5 to 30 percent, are used by the automotive industry for soldering radiator cores and for other applications. Tin contents as low as 2 percent are used in the canning industry. The electronics industry requires low-melting solders to protect heat-sensitive components, and so tin contents generally are around 60 to 65 percent.

Along similar lines, fusible alloy preforms can be used for manufacturing complex aerospace components that have internal cavities or as cores for forming fiberglass laminate or plastic parts. Fusible alloys also can be used to hold delicate or irregular-shaped workpieces, such as optical components, during manufacturing operations. After the component is polished or machined, the alloy is melted off and reused. Some fusible alloys are capable of sealing glass to glass or glass to ceramic in electronic devices, vacuum systems, and laboratory equipment. They can even be used as master alloys to add lead, bismuth, or tin to aluminum and other metals.

Precision Die Casting Parts and Assemblies

Why Precision Die Casting?

Precision Die Casting is the manufacturing process that pours or injects molten metals into molds made from steel, compressed sand, and other materials. This allows each part to be created with accuracy and repeatability.

Die Casting Material

Alloys that are suitable for die casting are those that are corrosion resistant and have optimal density. Our engineers assess the mechanical properties such as strength, hardness, and elongation when picking the right alloy to use for your die-cast. ;

The most common Precision Die Casting Parts are aluminum, magnesium, zinc, and copper. ;
