With our vast tool library and decades of materials science expertise, rely on Materion to manufacture solder preforms of the highest quality for enhanced performance. For optimal adhesion, our preforms are made with ultra-clean alloys for superior thermal and electrical conductivity. Our vast library of preforms includes:

  • Squares, rectangles, discs, washers & frames as well as custom, unique shapes
  • Extensive material selection of ultra-clean braze alloys for superior thermal and electrical conductivity
  • Lead-free alloys available in high-quality materials including gold and silver alloys, gold-tin alloys, gold-germanium alloys, gold-tin-copper alloys, and more
  • Standard thicknesses from 0.001” to widths up to 4.500”
  • Accurate, adjustable tools for low-volume requests


Materion’s gold alloy preforms provide essential benefits to properly manufacture your electrical product. Our preforms have a high reliability in joining gold-plated surfaces for hermetic sealing needed in microelectronics packaging. 


Our leading-edge technologies enable the production of superior sterling silver sheet known for its tailorable surface finish and shaped wire, offering excellent tensile strength. We produce our silver sheet and strip in a wide variety of sizes and thicknesses. Our capabilities include:

  • Custom design precious metal configurations to meet your needs
  • Widths are available from .100” to 6” wide
  • Common thicknesses of silver sheet and strip: .006” through .162” in Brown & Sharpe gauge increments
  • Silver braze alloys are also available in various widths and thicknesses

We manufacture our high-quality sterling silver wire, shaped wire and other precious metal wire in a variety of sizes and shapes to meet high demand in the electronics industry:

  • Rounds
  • Half-rounds
  • Squares
  • Triangles
  • Custom sizes and shapes


Operating multiple slitters simultaneously allows Materion to be the fastest supplier of pure silver sheet and strip for stamping, with an expedited turnaround time. We meet customers’ exacting requirements by slitting our wide coils of fine sterling silver sheet into smaller coils. Our silver sheet and strip can be used for almost any industrial application.

We manufacture our wire on coils or spools. Select the most appropriate metal for your applications, from .999 fine silver wire, platinum alloy wire, silver brazing alloys, and other precious metal wires. Whether your commercial use is for medical, military, defense, electronics, brazing and soldering, aerospace, or another industry, we can produce wire tailored to your commercial or industrial needs.
