Waukesha Foundry has earned a reputation as an innovator in the production of anti-galling cast components for food processing equipment.
Waukesha Foundry has developed a line of corrosion-resistant, nickel- and copper-base alloys that work in contact with stainless steel, Inconel®, Monel®, chromium plate and many other metals without galling or seizing. Appropriate for contact with food, our unique anti-galling alloys are used in applications where daily cleaning or sterilization is required and the use of lubricants is prohibited. All anti-galling testing for requirements certification is conducted on site.
Waukesha Metal 23BI
WM23BI is an anti-galling alloy with higher yield strength and hardness than our standard WM88. These characteristics help maintain a sharper edge on blades and similar components. It offers good corrosion resistance and can be used at high temperatures. WM23BI is readily castable and machinable.
Waukesha Metal 3
WM3 is specially formulated for excellent strength and corrosion resistance. This food-grade alloy has a copper base and can be used at extreme temperatures. It is well suited for homogenizers.
54C Alloy
This high-temperature, high-strength alloy has good corrosion resistance and can be used at extreme temperatures. The alloy's excellent self-lubricating qualities, due to the inclusion of silver, make it ideal for valve guides in aircraft engines that must operate in extremely hot temperatures. The 54C alloy affords exceptional wear resistance.
Cast Invar®
Invar® 36, the typical Invar material of choice, is a 36-percent, nickel-iron alloy, which has the lowest thermal expansion among all metals and alloys in the range from room temperature up to approximately 350° F. The alloy is ductile and easily weldable with machinability similar to stainless steel.
With a very low CTE (coefficient of thermal expansion), Invar plays an important role in elevated-temperature cured, carbon fiber reinforced composite tooling. These tooling materials must provide temperature resistance, very low CTE to match the composite cure temperature, vacuum integrity, thermal conductivity and machinability. The compatibility of the CTE of the Invar mold and the composite parts avoids distortion, induced stress and warpage. All this adds up to a material that meets the dimensional tolerance and production requirements for composite components.
Waukesha Metal 126
We developed WM126 as a copper base, anti-galling material for use in meat processing plants for form plates, plungers and vane pumps. WM126 is also well suited for gears, bushings and bearings. This alloy offers good strength and corrosion resistance and can be used at extreme temperatures. Note: WM126 is not an Ni-base alloy.
