What is Tungsten Metal Small Polished Discs 99.95% Purity?
Our Tungsten Metal Small Polished Discs 99.95% Purity are fabricated from ≥99.95% pure‑tungsten raw material. The high hardness and wear‑resistant properties of tungsten help the cutting contact disc keep stable sharpness under high‑temperature and high‑load working conditions.
Precision machining delivers accurate dimensions and polished flat surfaces, which support consistent cutting performance.
We supply technical guidance and full‑range quality inspection for each batch of Pure Tungsten Discs. Operation‑related maintenance suggestions are also available to extend component service life.

Powder Metallurgy Tungsten Discs are manufactured from ≥99.95%‑purity tungsten feedstock. High melting‑point and material hardness maintain stable performance under high‑temperature and high‑load operating conditions. Strict impurity control reduces particle release during polishing processes, supporting consistent surface‑treatment results and extending component service life.
High efficiency and durability:
Powder Metallurgy Tungsten Discs made from high‑purity tungsten deliver solid wear and corrosion resistance, reducing component replacement frequency under continuous operation.
Precise polishing effect:
The polished surface finish of Pure Tungsten Disc for Car Horn supports fine polishing work and stabilizes workpiece surface quality. Main deployment includes car horn contact assemblies.
Environmental protection and safety:
For Pure Tungsten Disks, high melting point enables stable mechanical behaviour under extreme operating temperatures. The material resists reaction with most acids, alkali, and salt media.
Application Integration of Tungsten Copper Button Contact
HVDC Contactors & Circuit Breakers
In 800V+ DC contactors, tungsten discs serve as the primary arcing contact, interrupting current flow under inductive loads. The high arc resistance and non-welding characteristics ensure reliable opening under short-circuit conditions.
Automotive Horn Switches
Automotive horn vibratory diaphragms need contacts to endure frequent high‑current pulses. Pure Tungsten Disc for Car Horn resists metal transfer and arc erosion, maintaining reliable horn performance throughout vehicle service life.
Smart Meter Latching Relays
For utility‑grade latching relays requiring contact closure without sustained contact pressure, Tungsten Discs deliver stable contact resistance and resist oxidation‑induced open circuits.
Industrial MCCB Breakers
Molded case circuit breakers use tungsten‑tipped contacts for short‑circuit interruption where the high‑temperature arc must be extinguished without contact welding or excessive material transfer. Pure Tungsten Disks satisfy such demanding interruption working conditions.
