One crucial property to understand in metalworking is thermal conductivity. The simplest definition of thermal conductivity is a material’s ability to transfer or conduct heat from one location to another efficiently. A more technical definition from Science Direct is, “Thermal conductivity can be defined as the rate at which heat is transferred by conduction through…

Introduction Bronze is a copper-based alloy that has been valued throughout history for its versatility, durability, and attractive nature. Bronze is composed primarily of copper with various combinations of tin, zinc, lead, and aluminum. This combination also produces brass. Brass contains a larger amount of zinc than tin, while bronze contains larger amounts of tin…

When considering the production of complex metal components, it is important to evaluate the costs associated with different metal casting methods. There are several factors that go into “all-in” costs. These factors include tooling and tooling maintenance, material costs and machining. Below is a comparison of the all-in costs of three popular metal casting processes:…

Investment casting (also known as lost-wax casting) is a common manufacturing process used to create metal parts with fine detail and tight tolerances. The investment casting method involves the creation of a tool, typically made from a high-grade aluminum alloy, that serves as a mold for wax. Hot wax or plastic is poured into the…

What Is Low Alloy Steel? In general, there are two categories of steel: Low alloy steel has low percentages of alloying elements such as chromium and nickel compared to stainless steel. As a result, low alloy steel does not have the heat, wear, or corrosion resistance provided by stainless steel. However, low alloy steel provides…

Casting is a manufacturing process of pouring molten metal into a mold to create a desired shape. Once the metal solidifies, the mold is removed, and the part is produced. Three similar casting processes are: die casting, investment casting, and sand casting. Selecting the appropriate casting method for your project is as important as selecting…

Copper vs. Brass vs. Bronze At MetalTek, one of the elements we work with is copper. The two primary copper alloys are brass and bronze. Brass is made of copper combined with zinc and bronze is an alloy made of copper combined with other elements, historically tin. MetalTek specializes in bronze alloys and does not…

Metal casting is precise and process orientated. With countless variables potentially affecting the result, casting inspection procedures must be rigorous. Inspection methods can vary between casting type, and different inspection methods are often used for a single casting. More than anything else, metal casting inspections provide customers with confidence that they received a quality casting. …
