Stainless Steel
Type 304 & 316 stainless steels for wet and no rust applications in a variety of sizes, straight or crimped. Highly corrosion and heat resistant and unlike carbon steel, stainless steel does not leave after-rust deposits when used on stainless steel, aluminium, and other high-strength alloys. However, once used on carbon steel it cannot be used on stainless steel or rusting can occur. Used in corrosive environments for general purpose cleaning, rust removal, deburring, edge blending, and roughing for adhesion. Stainless Steel is FDA approved and widely used in medical brushes, pharmaceutical brushes and food service brushes.
Hastalloy B3
A Nickel-Molybdenum alloy with excellent corrosion resistance to hydrochloric acid at all concentrations and temperatures, this exotic material is used when 316 stainless steel does not have the corrosion resistance properties required in certain applications.
Also withstands sulphuric, acetic, formic & phosphoric acids & other non-oxidising media, resisting pitting corrosion & stress corrosion cracking.
Carbon Steel
Available both tempered and non-tempered, in a variety of sizes, straight or crimped. This is a widely used metal fill material. It has excellent cutting ability and fatigue resistance for long brush life at a low cost. It is used for general-purpose cleaning, rust removal, deburring, edge blending, and roughing for adhesion. (We DO NOT supply Carbon brushes for motors)
Brass
The softest metal fibre available. Straight or crimped. Used for light to medium cleaning and luster finishing.
Phosphor Bronze
Phosphor bronze is non-sparking and about 1/5 as conductive as copper. Stronger than brass and lasts longer. Resists corrosion and fatigue due to flexing.
