Luois Metals is a reputable manufacturer and supplier located in Houston, USA, focusing on top-notch Tungsten Bars and Rods designed for outstanding performance in extreme temperatures and tough applications. Crafted from high-purity tungsten that meets ASTM and international standards, these products boast incredible density, a high melting point, and impressive resistance to corrosion and thermal creep. Available in a variety of diameters, lengths, and finishes—whether ground, centerless ground, or polished—these tungsten bars and rods are tailored to meet specific requirements. Industries around the globe depend on Tungsten for uses in aerospace, electronics, defense, and high-temperature furnace settings that demand superior strength, dimensional stability, and durability.
Tungsten Bars and Rods typically contain ≥99.95% pure tungsten, showcasing remarkable characteristics: an extremely high melting point (~3420 °C), a density of ~19.3 g/cm³, and outstanding hardness. Their tensile strength usually ranges from ~700 to 1000 MPa, with a high modulus of elasticity (~400 GPa). This material retains its strength and rigidity even at elevated temperatures and offers excellent thermal and electrical conductivity. Tungsten’s exceptional resistance to erosion, creep deformation, and chemical attack makes it perfect for harsh operating conditions. Precision manufacturing guarantees tight dimensional tolerances and a clean surface finish, making it suitable for critical industrial and scientific applications.
