Gray iron, or grey cast iron, is named after the gray color of the fracture it forms, which is due to the presence of flake graphite. It is the oldest and most common cast iron and the most widely used cast material based on weight. It is used for housings where the stiffness of the component is more important than its tensile strength, such as internal combustion engine cylinder blocks, pump housings, valve bodies, electrical boxes, and decorative or ornamental castings.
Ni-Hard is a white cast iron, alloyed with nickel and chromium suitable for low impact, sliding abrasion for both wet and dry applications. Ni-Hard is an extremely wear resistant material, cast in forms and shapes which are ideal for use in abrasive and wear environments and applications.
White Cast Iron
A type of cast iron with lower levels of carbon and improved tensile strength. These castings possess high compressive strength and excellent wear resistance. They tend to be used in wear resistant applications such as cylinder, or fluid flow applications.
WSF can produce for you a 15% and 25% Hi-Chrome alloy iron. Typically used in applications of wear resistance and long term heat resistance are required, such as impellers, turbines, and grinding applications. The iron expresses a very hard surface. These high-chromium alloys attribute their superior hardness to the presence of chromium carbides.
Ductile iron, also known as ductile cast iron, nodular cast iron, spheroidal graphite iron, spheroidal graphite cast iron. While most varieties of cast iron are brittle, ductile iron has much more impact and fatigue resistance, due to its nodular graphite inclusions that are spherical in shape rather than striated.
