Stainless Steel
Stainless steel is one of the most common metals poured for investment casting. Stainless steel is known for its exceptional corrosion resistance and versatility in critical industries such as food and beverage, medical, oil and gas, and petrochemical.

Aluminium
Aluminum is a lightweight, corrosion resistant alloy commonly used for investment cast components. At Milwaukee Precision Casting, Inc., we pour aluminum A356 for project critical parts such as pump impellers & housings, covers, plates, high velocity blowers, and more.

Carbon-Steel
Carbon Steel Casting utilizes carbon steel alloys for the precision investment casting process. For industries such as agriculture, firearms, and automotive that require strong, durable, and moderately machinable parts, carbon steel castings are commonly utilized.

Bronze
Milwaukee Precision Casting, Inc. is a trusted leader in the production of high-quality bronze investment castings, ranging from just a few grams to 25 pounds.

Tool Steel
Tool steel is utilized in investment castings that require high-temperature environments otherwise not considered corrosive. This is because tool steel alloys contain molybdenum to increase the alloy’s melting point, but not enough chromium to be considered a corrosion resistant steel.

Brass & Copper
Milwaukee Precision Casting, Inc. is a leader in the manufacturing of brass cast parts, from as small as a few grams up to 25 pounds.
