Note: Special requests will be settled by negotiation between both parties.
While Tungsten Plates and tungsten rods share the same base physical properties (like an extreme melting point of 3,422°C and high density), their cylindrical shape and manufacturing orientation make rods behave differently during fabrication and application.
