Characteristics

Ultra-High Purity Guarantee

Tungsten content ≥99.95% with extremely low impurity content, effectively avoiding impurity interference on material performance, suitable for high-end application scenarios sensitive to purity.

Extreme High-Temperature Resistance

Melting point up to 3410℃, maintaining stable mechanical properties below 1600℃, capable of withstanding extreme high-temperature environments, making it the preferred pure tungsten material for high-temperature scenarios.

High Strength and Hardness

Hardness up to HRC35-45 at room temperature, excellent tensile strength and outstanding wear resistance, capable of bearing high loads and friction losses, with service life far exceeding ordinary metal materials.

Excellent Electrical and Thermal Conductivity

Conductivity is about 30% of copper, with good thermal conductivity and extremely low thermal expansion coefficient (only 1/3 of steel), suitable for scenarios such as precision electronics and heat dissipation components.

Stable Chemical Properties

Not easy to react with oxygen, water vapor, etc. at room temperature, resistant to acid and alkali corrosion (except for a few media such as hydrofluoric acid and concentrated nitric acid), suitable for complex corrosive environments with strong chemical stability.

Good Processing Adaptability

Can be formed through various processing methods such as forging, rolling, cutting and welding. Toughness is further improved after vacuum annealing, which can meet the manufacturing needs of complex structural parts with low processing loss.

Non-Magnetic and Radiation Resistance

No magnetic interference, suitable for scenarios sensitive to magnetism such as electronic instruments and navigation equipment; has certain radiation resistance, and can be used in nuclear industry related equipment.

Production Process

Raw Material Preparation: The foundation for product quality is laid by choosing high-purity tungsten concentrate, preparing high-purity tungsten powder (purity ≥99.95%) by various purification procedures such roasting and reduction, and closely controlling powder particle size and purity.
Powder Forming: Mix high-purity tungsten powder with special binder in precise proportion, press and form through molding, isostatic pressing and other methods to obtain tungsten blanks with uniform density and complete structure.
Sintering Treatment: To create high-purity tungsten ingots or tungsten blanks, place the produced blanks in a high-temperature sintering furnace and sinter under vacuum or hydrogen protection to eliminate binders and accomplish densification.
Pressure Processing: Choose between the forging and rolling processes based on the product's thickness and performance needs. Forging is appropriate for processing medium-thickness plates to increase material density, while rolling is appropriate for producing thin plates to accurately control dimensional precision.
Vacuum Annealing: To remove processing internal stress, optimize grain structure, and enhance material toughness, plasticity, and high-temperature stability, place the processed tungsten plates in a vacuum annealing furnace and apply a heat preservation treatment at a particular temperature.
Finishing and Inspection: Make sure the product's dimensions are accurate, its surface is qualified, its purity satisfies standards, and it has a material inspection report and quality certificate attached by leveling, cutting, surface treatment (polishing, pickling, etc.), non-destructive testing (ultrasonic, radiation testing), and other procedures.
