Copper and Copper Alloys

Strength and versatility under harsh conditions

Thin-rolled copper and copper alloys from Arnold Precision Thin Metals (PTM) serve a broad range of needs. This versatile material is used in a variety of electrical products, heat exchangers, solar collectors, piping and other applications that require strength and corrosion resistance. Copper is often the best solution for applications that require excellent conductivity, strength and formability. Cooper and its alloys are generally non-magnetic. Copper alloys are also ideally suited to minimise bacterial levels on touch surfaces. To meet these needs, PTM offers its customers copper strip materials in a wide variety of thicknesses and alloy compositions.

Key Applications and Uses

  • Batteries
  • Miniaturisation of electronic devices
  • Cable and component shielding
  • Printed circuit boards
  • Antimicrobial surfaces


Available in all grades and tempers

Arnold PTM produces thin and ultra-thin strip in a wide range of tempers. The most common grades requested include C101, C110, and BeCu 172, but we can source and roll all copper and copper alloy grades. Contact us to discuss your requirements.
