cast alloy from jiachuan's blog

A wide range of casting alloyfacilitates selection of the most suitable and cost-effective material for specific application requirements. Each of these cast alloys has its own physical and mechanical properties. They also have their own casting features such as:

Solderability

machinability

Corrosion resistance

Heat treatment characteristics

Bronze is without a doubt the most versatile class of bearing materials, with a wide range of properties to choose from in a variety of alloys and compositions.

Furthermore, continuous research into alloying elements often leads to the invention and development of stronger and more suitable casting alloys to meet the demands of industrial applications. Choosing the right casting method and the most suitable alloy are two main factors that help to achieve a specific cost level.

There are two main categories of casting alloys:

ferroalloy

Ferrous alloys are iron-based alloys that have a wide range of uses in a wide range of industries due to their flexibility to meet strength, toughness and impact for a variety of industrial applications.

steel

The properties of steels determined by dispersion strengthening depend on the amount, size, shape and distribution of cementite (Fe3C).

These factors are controlled by alloying and heat treatment.

steel surface treatment

Surface heat treatment: The surface is rapidly heated, quenched, and then tempered.

Carburizing: Carbon diffuses to the surface to increase the carbon on the surface.

Nitriding: Similar to carburizing, but nitrogen (N) is used instead of carbon.

Stainless steel

Ferritic stainless steel (BCC): up to 30% Cr and less than 0.12% C. Good corrosion resistance.

Martensitic stainless steel: Cr < 17%. Heat treatable, able to form martensite in other phases.

Austenitic stainless steel (FCC): Ni is an austenitic stabilizing element.

cast iron

Grey cast iron: interconnected graphite flakes in a pearlite matrix. Vibration reduction effect is good.

White cast iron: Used for its high hardness and wear resistance. Martensite can be formed.

Malleable Iron: A heat treated unalloyed 3% carbon white cast iron.

Ductile Iron: The addition of magnesium (Mg) causes nodular graphite growth.

Non-ferrous alloys

Non-ferrous alloys are completely iron-free and are generally more expensive than ferrous alloys. Copper alloys are the largest product group of these alloys. Brass and bronze are the most popular copper alloys.

Brass made from copper and zinc alloys. Most varieties of brass are easy to form and have a pleasing appearance.

Copper is mainly alloyed with tin to make bronze.
