There are two distinct varieties of expanded stainless steel mesh used for baskets: standard and flattened. The term “standard expanded metal” refers to the metal as it comes out of the expanding machine. On the other hand, flattened expanded metal is what happens when standard expanded metal...
Expanded Metal Mesh Expanded metal is made by feeding sheets or coils into an expanding machine, equipped with a 'knife' designed to cut it to produce a particular mesh pattern. It's sheared and stretched in a single process, then cut into sheets or wound onto coils...
Tungsten carbide is used to machine non-ferrous metals such as aluminum and copper. It is also used in chipless forming processes, where materials are deformed into specific shapes through methods like rolling or extrusion. Tungsten carbide-tipped tools are commonly used for machining cast iron and...
