Brush Wellman offers a variety of copper mold alloys to fit your every need. The MoldMAX^® copper beryllium alloys are MoldMAX HH^® (High Hardness), MoldMAX LH^® (Low Hardness) and MoldMAX SC (Super Conductivity). Brush Wellman also offers non-beryllium alloys in MoldMAX XL^® and MoldMAX V^®. 

All MoldMAX products are high performance alloys specifically designed for the plastic processing industry. These alloys offer a unique combination of thermal conductivity and strength that provides important benefits for the molding process. 

WHY USE BRUSH WELLMAN MOLD ALLOYS 

THE MOLDMAX^® ADVANTAGE 

Through the unique combination of thermal conductivity and strength available in The MoldMAX product line, these copper mold alloys provide: 

• Shorter cycle time 
• Improved plastic part dimensional control 
• Better parting line maintenance 
• Excellent corrosion resistance 

MoldMAX  provides strength and wear resistance similar to that of many tool steels. In addition, MoldMAX offers a thermal conductivity up to ten times greater than steel and comparable to aluminum. MoldMAX is typically specified for: 

• Injection mold components and cavity inserts 
• Blow mold pinch offs, neck rings and handle inserts 
• Hot runner system injection nozzles and manifolds 

MoldMAX SC provides the highest thermal conductivity available in a mold material…ten times greater than steel and twice that of aluminum. MoldMAX SC also offers a hardness and strength exceeding aluminum. MoldMAX SC is specifically designed for foam processing, hot runner systems, blow molds and other applications where maximum heat removal or control is required.
