Copper Based Alloy Casting
Copper alloys are metal alloys that have copper as their principal component. They have high resistance against corrosion and the best known traditional types are bronze, where tin is a significant addition, and brass which uses zinc instead.
With Copper Based Alloys we are experts in sand casting the following:
LG2and LG4 more commonly known as Leaded Gunmetal Bronze has excellent machinability and great wear resistance with a high resistance to corrosion. This makes it a great all round option often used wear pressure tightness is required such as valve and pump bodies. It also is ideal for plaques and will produce a high quality polished surface
PB1 and PB2 or Phosphor Bronze have a good resistance to cold, corrosion and sea water but are great for use where high mechanical strength and high fatigue strength are needed. Typical applications include load gears and worm drives that have some high speeds as well as high loads. It also performs well under impact and loading so we’re often casting bushes, bearings and impellers in these metals.
AB2 is Aluminium Bronzestrong> which has very high strength, wear and is highly corrosion resistant. A key feature is also its ability to perform through a temperature range of -200c to 200c. High strength cast bushes and cast bearings typically used in aerospace applications are a common casting.
HTB3 or High Tensile Brassstrong> is an option for engineering castings where high wear resistance and high loads are encountered.
LB2 and LB4 are Leaded Brassstrong> alloys which tolerate moderate loading, impact loading and pounding. We regularly use these alloys to cast bearings for high speed pumps, impellers or where high corrosion resistance is required. Or its equally suitable for architectural brackets and also for some artistic applications such as plaques.
DCB or Die Cast Brassstrong> can be die cast as effectively as zinc-based alloys. Most commonly its used to create washers, camshaft components, and decorative products due to the distinctive coloring and potential for surface finishes. Typically, a brass alloy consists of 60 percent copper, 40 percent zinc, and 2 percent aluminum, but there are many variations on this mixture. DCB is capable of yielding products with a durable surface and highly accurate interior specifications and is used in sand casting as well as die casting.
