Nickel alloy investment castings are otherwise known
as monel investment castings. Nickel and cobalt alloy investment
castings carry some of the same characteristics of stainless steel investment
castings such as abrasion resistance. This abrasion resistance is
perhaps the most popular feature of cobalt and nickel alloy investment
castings.

Monel investment castings are typically used in the
energy industry where abrasion resistance is extremely important on parts
such as pumps and steam valves.
Nickel alloy and cobalt alloy investment castings can
be very difficult to process using lost wax casting. The parts must
be slow cooled over a period of twenty-four hours to avoid heat tears
and cracking. Cobalt and nickel alloy investment castings are extremely
fragile prior to heat treat and must be handled carefully. The raw
materials for nickel and cobalt alloy investment castings are the most
expensive with the exception of precious metals. Because of their
inherent abrasion resistance secondary operations such as machining are
very time consuming. For these reasons these are the most expensive
types of castings.
While we are able to produce nickel alloy investment
castings and cobalt alloy investment castings, at our China foundries
we encourage our customers who are not familiar with these alloys to utilize
less expensive investment casting alloys with similar mechanical properties.
