Wear is probably the most common cause of material replacement in the industry. Bushings and bearings are common examples of components which must provide metal-to-metal wear resistance. Wear is a universal constant in moving equipment in all applications. In some applications like food processing, the use of certain materials that provide superior wear resistance (copper-based…

About 60% of the nickel in the world ends up as a component of stainless steel. It is selected because of its strength, toughness, and resistance to corrosion. Duplex stainless steels typically contain about 5% nickel, austenitics around 10% nickel, and the super austenitics over 20%. Heat resistant grades often contain over 35% nickel. Nickel-based…

How strong is copper? The answer is it depends on which copper-based alloy you choose. You can achieve superior corrosion resistance and/or durability in applications that require wear and galling resistance. Copper is a heavy metal that can provide the strength equivalent of steel. But first, let’s differentiate between two copper alloys – brass and…

MetalTek offers more metal casting process diversity. Your ability to source centrifugal, sand, investment, HPLT, or continuous cast products from a single company is not available anywhere else in the world. Not sure which precision casting process is right for your components or application? Read the below article on what is casting and its types.…

Sand Casting Sand casting can be traced back to earlier than 1000 B.C. It is widely accepted as the oldest known casting process. The sand-casting process has evolved significantly since the beginning. But the process of how to sand cast has not strayed. The cast molding process is basic, create a cavity in the shape…

Benefits of Using Sand Casting 1. Nearly any alloy: Sand castings can be readily produced in nearly any ferrous or non-ferrous alloy. Some other casting processes will melt and pour super-alloys in a vacuum, but that is not typically done as a sand casting. Some materials cannot be “worked”, and must be produced as a…

While metal casting might be the best process to manufacture a wide range of components, depending on your needs, the forging process could be the best option. Or vice-versa. This is why it helps to know the key differences between forging and casting. So here are 5 things to consider when deciding if a casting…

Ferrous alloys (ferro alloys) or metals are metals that consist mostly of iron (Fe). Steel is an iron-based alloy containing typically less than 1% carbon, where iron frequently contains 2% or more carbon. Iron and steel are widely available, strong, cheap, and can be shaped by casting. Ferrous alloy properties can be improved by heat…

By way of definition, heat-resistant applications typically occur above 1200°F/670°C and require the use of materials that have enhanced resistance to oxidation and other environment-specific gases and mechanical property degradation. Performance in these high-temperature environments is indicated by acceptable levels of tensile strength, stress rupture life, and creep strengths that correspond to the required time…

Tin Bronze alloys consist of copper-based materials with the major alloying element being tin. The presence of tin provides high mechanical properties, the offset being that the addition of tin adds to the metal cost. The high tin bronzes, however, are particularly suited for certain applications for which the less expensive bronzes are not suitable.…
