Expanded metal

Expanded metal It has various other applications in addition to batteries,
such as golf shafts and tennis racket frames.

Features of expanded metal

Expanded metal is a mesh-like metal material that is made by making cuts to a metal foil in a zigzag manner and is expanded with a mold (expand processing). Expand processing to 1 m of material expands it by 2 to 4 times.

This processing can be done to various types of metals in addition to steel.

  • Aluminum
  • Copper
  • Stainless steel
  • Titanium
  • Nickel
  • Monel
  • Various resins
  • Various paper types

(This process can be done to any material with an expansion capacity of 15% or more.)

Many applications are available.
