Fusible Alloy Preforms
Fusible alloys are stable and can either be classified as eutectic or non-eutectic. Eutectic alloys have the lowest melting point possible—the temperature at which the material is solid is equal to the temperature at which the material is liquid. Non-eutectic alloys begin to melt at one temperature and then enter a slushy state before they fully melt at a higher temperature. Low-melting alloys are available in a variety of forms: cake, ingot, bar, shot, wire, stick, strip, and custom shapes.
Many of the low-melting alloys have good thermal conductivity, can be remelted and reused, and have combinations of elements that cause them to expand during solidification without contracting during cooling. These characteristics make fusible alloys versatile, allowing them to be used in a diverse amount of applications, including common everyday items such as fire sprinklers and pop-up turkey timers. In both cases, the alloys begin to melt at a specific temperature, triggering a mechanism that either opens a valve to let water flow or pops up a button to indicate the turkey is done.
Manufacturers can use fusible alloys to solve problems and save time and money. For instance, using a fusible alloy when bending thin-walled tubing can help prevent kinks or wrinkles. Tubes are lubricated, filled with a low-melting alloy, and cooled so that the alloy solidifies inside, supporting the tube’s wall. Once bent, the tube is reheated to liquefy and remove the fusible alloy.
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. ;
Aluminum Die Casting
Aluminum alloys are our most common material for die cast parts. ; Aluminum die-cast parts have a lot of advantages which allows us to create parts with high dimensional stability with complex part geometries and in a very efficient way.
Zinc Die Casting
Zinc alloys are a strong, durable, and cost-effective material. They provide a very good combination of strength, toughness, rigidity, and cast-ability with superior finishing capabilities.
