Lost Wax Casting Alloys Overview

The lost wax casting process is highly versatile and can be applied to nearly all ferrous and nonferrous metals. As a professional investment casting manufacturer, SIMIS provides both ferrous and nonferrous alloy castings tailored to customer requirements. Below is an outline of the main alloys used in lost wax casting.

Ferrous Alloys

Ferrous alloys are iron-based materials widely valued for their strength, toughness, and impact resistance. Common ferrous alloys used in casting include carbon steel, stainless steel, alloy steel, and various grades of cast iron.

Carbon Steel: Contains carbon with minor alloying elements such as manganese or aluminum, offering balanced strength and affordability.

Alloy Steel: Enhanced with elements like chromium, molybdenum, vanadium, or nickel to improve mechanical properties.

Stainless Steel: Corrosion-resistant alloys with chromium and/or nickel, widely used in demanding environments.

Cast Iron: High carbon content alloys available in ductile, gray, and white grades, each with distinct properties.

Cast Steel: Produced by pouring molten iron into molds, offering versatile applications across industries.

Nonferrous Alloys

Nonferrous alloys are selected for their unique mechanical and chemical characteristics. In lost wax casting, the most common nonferrous materials are aluminum and bronze, with A356 aluminum being a widely used grade.

Key Advantages of Nonferrous Alloys:

Lightweight with high strength-to-weight ratio

Excellent resistance to chemical and atmospheric corrosion

Nonmagnetic properties suitable for electrical and electronic applications

High melting points and thermal stability
