Cobalt and nickel investment castings, also known as monel alloys or super alloys, provide high end corrosion and abrasion resistance at the most extreme temperatures. When it comes to investment casting, Cobalt and nickel share many mechanical properties with stainless steel castings, but are designed for even greater strength and oxidation resistance.
Reduction or elimination of high machining costs associated with nickel and cobalt
Intricate, near-net shape parts achievable without machining
Easily convert multiple parts into single assemblies
Thin walls for weight reduction opportunities
Surface texture of 125 RMS or better
Tolerances within +/- .005 inches per linear inch
Highly complex dimensional geometry
Due to their impressive mechanical properties and heat resistance, nickel and cobalt both enjoy long service high resistances to oxidation carburization.
While superalloy cobalt and nickel investment castings are typically more expensive than other alloy types, these superalloy castings offer unmatched temperature resistance, surface stability under high stress conditions, and overall hardness
Nickel is commonly used in high temperature liquid and gas flow control. Nickel is one of the few alloys capable of resisting the high temperatures these pipes produce.
