RÖNTGEN Bi-Alfa Cobalt WS ALU Band Saw Blade – cutting blade for aluminium and non-ferrous metals

The RÖNTGEN Bi-Alfa Cobalt WS ALU Band Saw Blade is an advanced cutting blade engineered for precise cutting of non-ferrous metals – including aluminium, copper, brass, and their alloys. With the use of HSS M42 high-speed steel, a widened tooth set, and an aggressive rake angle, the WS ALU metal-cutting blade ensures efficient chip evacuation, minimises the risk of blade binding, and provides long-lasting durability even during continuous production cycles.

Main advantages of the RÖNTGEN Bi-Alfa WS ALU bandsaw blade

• Wide tooth set – increased kerf for excellent chip clearance and reduced clogging.
• Aggressive rake angle – ensures smooth penetration into soft, ductile non-ferrous metals.
• High wear resistance – achieved with HSS M42 (8% cobalt) cutting edges.
• Optimised tooth geometry – delivers uniform cutting and reduced cutting resistance.
• Extended blade life – minimises material adhesion and overheating during continuous use.

Construction and technology

The WS ALU blade was designed specifically for cutting non-ferrous metals that tend to stick to the teeth and cause clogging. The working section is made of HSS M42 high-speed steel, providing excellent hardness and heat resistance for consistent edge retention. The widened tooth set creates a larger cutting channel, reducing the risk of binding and improving chip evacuation. The aggressive rake angle allows for smooth penetration into soft alloys without excessive feed force – essential when cutting lightweight, ductile materials.

Precision and performance

The WS ALU cutting blade delivers fast, clean cuts while reducing friction and heat build-up. The optimised tooth geometry and wear-resistant materials ensure stable operation in long production runs. Resistance to chip adhesion and lower cutting forces directly translate into lower energy consumption and longer tool life between replacements.

Applications
