(CRS) Cold Rolled Steel:..(CRS) Cold Rolled Steel: at the steel foundry in a cold state CRS is pressed into a sheet. We typically use CRS steel sheets.
Hot Rolled Steel (HRS):..HRS is formed into a sheet in a molten state and rolled flat while still hot. HRS is usually of less quality than CRS, is more difficult to machine due to variable composition in the metal.
Stainless Steel (CRES):..CRES is an alloy based upon steel and chromium and it is classified by its ability to resist corrosion. The gauge thickness is equivalent to typical steel. Stainless-steel is significantly harder than common steel and isn't easy to use in a few aspects. Our lasers think its great and have absolutely no issues with it. It is challenging to punch, and can be difficult to weld.
Aluminum: There are various mixtures of aluminum, which are called alloys, that are mixed with other metals, often with zinc, copper, magnesium, manganese or silicon. There are too many alloys of aluminum to list. The 4 digit code after the number is the temper or the tensile strength of the alloy that ranges from soft T0 to T6 and full hard T6. 5052-H32, 6061-T6, 6061-T4 Metal Werks uses for most of our parts.
