Platinum Mesh Description

Platinum (Pt) is a grayish-white precious metal with high density, high ductility, and low reactivity. It is a transition metal. Platinum Mesh is made from high-purity platinum with a purity of 99.95% or 99.99%, featuring excellent corrosion resistance, high-temperature stability, and outstanding conductivity. It usually consists of woven thin wires of various thicknesses, assembled in a way to form a stable sheet. The plain weave and twill weave are the most common types. Heeger Metal specializes in manufacturing high-quality platinum meshes with various specifications for multiple industrial and research applications.

Platinum Mesh Applications

  • Catalysis: They can be used in catalytic converters to accelerate chemical reactions, particularly in automotive exhaust systems.
  • Electronics: They serve as contacts or electrodes in high-performance electronic devices, such as thermocouples and sensors.
  • Chemical Processing: They are used as catalyst supports or in the production of various chemicals due to their inertness and stability under harsh conditions.
  • Medical Devices: They are used in medical devices, including pacemakers and other implants, because of their biocompatibility and resistance to corrosion in the human body.
  • Laboratory Applications: Used in laboratory equipment like crucibles and reaction vessels where high temperatures are involved.

Platinum Mesh Packaging

Platinum Mesh is carefully placed in wooden cases or cartons with additional soft materials to support and prevent shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
