Tungsten Foil/Strip/Ribbon Tolerances

Tungsten foil, strip, and ribbon are produced with precise tolerances to meet specific application requirements. Tolerances typically cover thickness, width, and length, ensuring that the material fits the intended design and performance criteria. Custom tolerances can be specified depending on the customer’s needs.

Thickness (mm)	Tolerances for Thickness (mm)		Width (mm)	Tolerances for Width (mm)	Length (mm)	Tolerances for Length (mm)

Tungsten Foil/Strip/Ribbon Production Process

Tungsten foil, strip, and ribbon are made of high-purity tungsten and tungsten alloy ingots through hot rolling, cold rolling, and annealing to achieve the desired thickness, strength, and ductility. Additional treatments such as polishing and chemical etching may be applied to meet specific requirements for particular applications. Here is the typical production process:

• Raw Material Selection: Tungsten ingots or powder are selected based on purity and quality requirements.
• Melting and Casting: Tungsten is melted in a vacuum or inert gas atmosphere and cast into ingots.
• Hot Rolling: The ingot is heated and passed through rollers to reduce the thickness and achieve the desired shape.
• Cold Rolling: Further reduction of thickness is achieved at room temperature, improving the material’s surface finish and mechanical properties.
• Annealing: The material is heat-treated to relieve internal stresses and improve ductility.
• Pickling and Polishing: The surface is cleaned using chemical treatments to remove oxides and improve appearance.
• Final Cutting: The material is cut into foil, strip, or ribbon forms, depending on the specific application requirements.

Tungsten Foil/Strip/Ribbon Applications

• Electronic Components: Tungsten foil, strip, and ribbon, with their high melting points and low coefficients of thermal expansion, are widely used in the manufacturing of electronic components, especially those that operate in high-temperature and high-pressure environments.
• Aerospace: Due to their high density and strength, tungsten foil, strip, and ribbon are used in the aerospace industry for making shields and radiation-resistant materials to withstand extreme temperatures and radiation.
• Medical Field: Tungsten foil, strip, and ribbon are used to produce radiation therapy equipment, providing effective radiation shielding.
• Thin Film Resistors: Thanks to their excellent electrical conductivity, tungsten foil, strip, and ribbon are commonly used in the fabrication of thin film resistors.

Tungsten Foil/Strip/Ribbon Packaging

The tungsten foil, strip, or ribbon is carefully placed in wooden cases or cartons with additional support from soft materials to prevent any shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
