Product Overview

Number 150 Cast Iron Powder is a cast iron powder supplied in 1 inch x 1 inch square piece form for powder metallurgy and specialized industrial applications requiring iron powder with the composition characteristics of cast iron. Cast iron powder provides a combination of iron, carbon, and silicon that distinguishes it from pure iron powder in applications where the carbon and silicon content of cast iron is beneficial to the sintered or processed part properties. The square piece form provides consistent unit geometry for accurate charge measurement and convenient handling in production operations. Available in standard unit packaging for industrial use.

Frequently Asked Questions

Common technical inquiries regarding #150 Cast Iron Powder

Cast iron powder contains carbon (typically 2-4%) and silicon (typically 1-3%) that are absent in pure iron powder. In powder metallurgy applications where the sintered part requires the hardness, wear resistance, or machinability characteristics associated with cast iron microstructures, cast iron powder is the correct specification. Pure iron powder produces softer, more ductile sintered parts; cast iron powder produces harder parts with higher carbon content in the sintered matrix, suitable for wear-resistant components and friction materials.

Cast iron powder is typically sintered at 1900-2100°F in a controlled atmosphere — reducing or neutral atmosphere prevents surface oxidation that would inhibit particle bonding. The carbon content requires careful atmosphere management: in a hydrogen atmosphere, carbon can be partially removed by decarburization; in an endothermic atmosphere, carbon potential must be controlled to maintain the target carbon level in the sintered part. Consult the specific sintering furnace manufacturer's recommendations for carbon potential control when processing high-carbon iron powders.

The square piece form is suited to applications where cast iron is used as a charge addition rather than as a loose powder — including foundry additions to iron melts for chemistry adjustment, brazing paste formulations where cast iron filler is required, and specialized friction material manufacturing. Loose cast iron powder (fine mesh grades) is more common for conventional powder metallurgy pressing and sintering. The square piece form provides handling convenience and consistent weight per piece for charge addition applications.
