In addition to plain carbon steel, other materials can be made into metal wool. Aluminum, Brass, Bronze, Copper, and Stainless steel wool are available.

Exotic metal wools posses several important properties that make them suitable for use in a wide range of different applications.

Benefits

• Gentle Abrasiveness - Unlike sandpaper and other grit-based abrasives that scratch away material with sharp points, metal wool fibers perform like thousands of tiny planes on a surface. The result is a smoother surface after sanding and a better result after finishing.
• High Aspect Ratio - The shaving of wire into metal wool is an economical method to produce fine metal fibers. Metal fibers have many chemical and physical properties that make them ideal for many applications including thermal management, chemical reactions, electrochemistry, and composite reinforcement.
• Corrosion Resistance - Stainless steel, brass and bronze wool offer excellent corrosion resistance when used in wet applications, or where exposure to the environment would cause discoloration or degradation. Copper wool offers limited corrosion resistance over plain carbon steel wool.
• Design Flexibility - Metal wool can be efficiently manufactured into many forms that allow easy integration into final applications. From chopping into low aspect ratio fibers for friction materials to forming textile-like metal fiber fabrics, metal wool is the material of choice for many OEM applications.

Materials

Stainless steel wool is made from AISI 434 stainless steel. Brass wool is made from alloy 270 (65/35) brass. Bronze wool is made from a lead-free Bronze alloy. Copper wool is made from >99.9% pure copper.
