From September 26 to 30, 2026, ASTRO’s 68th Annual Meeting — the world’s most influential annual event in radiation oncology — will take place at the Boston Convention and Exhibition Center (Thomas M. Menino). Luoyang Combat Tungsten & Molybdenum Materials Co., Ltd. officially participates in the exhibition at Booth 736, presenting alongside leading enterprises and professionals in the global radiation oncology community.

Exhibition Focus: High-Density Medical Shielding Components & Precision Machined Parts

Combat’s exhibited products center on high-density tungsten alloy medical shielding components and precision machined parts. Catering to radiotherapy equipment, nuclear medicine imaging, radiopharmaceutical handling and other scenarios, we deliver integrated solutions ranging from raw materials to finished products.

Core Products & Application Scenarios

Radiotherapy Equipment Shielding Assemblies Thanks to outstanding radiation attenuation performance, high-density tungsten alloy is fabricated into MLC leaves, collimator assemblies and chamber shielding structures for radiotherapy systems. The high density of tungsten alloy enables efficient radiation blocking within confined space, ensuring precise beam targeting of tumor lesions while minimizing scattered radiation damage to adjacent healthy tissues.

Shielding Components for Nuclear Medicine and PET/SPECT Devices To meet frequent handling requirements for radiopharmaceuticals such as F-18, Tc-99m and I-131 in nuclear medicine workflows, Combat supplies syringe shielding sleeves, vial shield containers, isotope generators and transport shielding vessels for radiopharmaceuticals. Featuring lightweight and compact design, tungsten alloy shields effectively reduce extremity radiation dose for medical staff and ease operational burden. In PET, SPECT and gamma camera systems, tungsten alloy shielding grids and septa absorb off-axis scattered radiation, improving detector signal-to-noise ratio and imaging accuracy.

Precision Collimation & Detection Components Combat manufactures a full range of precision collimators including parallel-hole, pinhole and coded-aperture types, plus custom parts such as detector shielding housings. High-density tungsten alloy structures effectively suppress radiation penetration and leakage to prevent imaging artifacts and blurriness, meeting stringent requirements for thin-wall, high-precision structures demanded by high-resolution medical imaging.

Machining Capacity & Quality Assurance

Combat possesses full-spectrum manufacturing capabilities spanning powder metallurgy through precision machining. Medical-grade high-density tungsten alloy is produced via liquid-phase sintering, achieving over 99% of theoretical density with pore-free, defect-free finished parts and consistent, stable shielding performance. Subsequent processes including CNC precision turning and electrical discharge machining (EDM) deliver medical-grade surface finish and ultra-tight tolerance accuracy to satisfy requirements for sterile assembly and long-term stable operation.

Our product portfolio covers W-Ni-Fe and W-Ni-Cu grades with tungsten content from 90% to 97%. Custom material formulations are available based on radiation type, energy level and application environment. Non-magnetic W-Ni-Cu alloy is suitable for applications with magnetic permeability constraints.

Invitation to Visit Booth 736

Combat sincerely invites global radiotherapy equipment manufacturers, medical physicists, nuclear medicine institutions and industry partners to visit and communicate at Booth 736. Our on-site team will introduce material selection, machining solutions and customized services for high-density tungsten alloy medical shielding components, and explore potential collaboration opportunities in radiation oncology.
