Tungsten Heavy Alloy High-Density Bushing ø70xø35x68 mm 19.1 g/cm³ Shielding Collimator Sleeve for Radiotherapy & NDT

Product Overview: Precision Engineered for High-Density Shielding & Mechanical Rigidity

This precision-machined tungsten heavy alloy bushing is manufactured to exacting specifications: outer diameter 70 mm, inner bore 35 mm, overall length 68 mm, with a remarkable material density of 19.1 g/cm³.

This bushing delivers exceptional dimensional stability, high tensile strength, effective radiation absorption, and superior wear resistance. It is the optimal choice for high-performance collimator assemblies, radiation shielding components, guiding sleeves, and wear-resistant industrial machinery operating in high-stress environments.

Specification	Value
Density	19.1 g/cm³ (approximately 60% denser than lead, >130% denser than steel)
Outer Diameter	70.00 mm (tolerance customizable)
Inner Diameter Bore	35.00 mm (tolerance customizable, precision-ground finish available)
Length	68.00 mm (tolerance customizable)

Why Choose This Tungsten Heavy Alloy Bushing?

Exceptional Radiation Shielding: With density 19.1 g/cm³ and tungsten's high atomic number (Z=74), this bushing provides superior attenuation of gamma rays and X-rays. For the same shielding effectiveness, the required thickness of tungsten alloy is only 60-75% that of lead.
Outstanding Mechanical Properties: Unlike lead—which is soft and prone to creep—tungsten heavy alloy offers excellent strength, hardness, rigidity, and dimensional stability. The material can be machined to precise tolerances, resisting deformation under load or during thermal cycling over a long service life.
Design Flexibility: Tighter device integration. This bushing can be integrated as a collimator aperture ring, a structural shielding sleeve, a precision guide bushing, a bearing spacer, or a wear-resistant shaft liner, depending on the specific application requirements.
Non-Toxic & Compliance: This bushing is lead-free, RoHS-compliant, and non-toxic—eliminating the disposal hazards and regulatory burdens associated with lead shielding.
Superior Corrosion & Wear Resistance: Tungsten alloy provides excellent resistance to moisture, chemicals, and abrasive wear. The bushing maintains its precise dimensions and surface finish over millions of operating cycles, reducing replacement frequency and total cost of ownership.
High-Temperature Stability: With a melting point of approximately 3400°C, tungsten alloy maintains structural integrity across the wide temperature excursions encountered in demanding shielding and mechanical applications.
