Beryllium Copper or Copper Nickel Alloys

• Even producers of beryllium copper
• Alloys prototyping manufacturing have been
  offering copper alloys
• without beryllium due to competition
• and continuing issues associated with
• beryllium-containing alloys
• and
• injection mold making

Copper Alloy Usage

• An informal survey of plastic injection mold
• And plastic mold-manufacturer still shows a large
• percentage believing that copper alloy
• usage in their molds is of little to
• no benefit.

The Copper Alloy Solution

• One example is there must be greater
• importance placed on water flow rates
• and controlling, such in molds when
• using copper alloys. To maximize the
• benefits of prototyping manufacturing copper
  alloys the design
• of water flow should be to maintain
• turbulent flow versus laminar flow.
