China's One-Stop Rare Metal Factory
Shaanxi Zhongheng Weichuang Metal Materials Co., Ltd. is a source manufacturer specializing in rare and refractory metals such as niobium hafnium alloy c103, tantalum, niobium, zirconium, hafnium, tungsten, cobalt, nickel, titanium, etc.
We have our own factory, complete melting and processing production line, independent testing laboratory, and global export team to ensure that every batch of products can be traced, controlled, and verified from raw material entry to finished product delivery.
Our products are widely used in high-end fields such as aerospace, semiconductors, nuclear industry, medical equipment, petrochemical energy, etc., providing long-term stable supply of rare metals to global customers.
Testing Capabilities
Our testing laboratory covers the entire process testing capability from raw materials to finished products, which is the key basis for determining whether it is a real factory.
1
Raw Material Testing (Chemical&Purity Testing)
ICP-OES composition analysis (can detect the purity of elements such as Ta, Nb, Zr, Ti, Ni, V, etc.)
XRF metal spectroscopic analysis
Oxygen/Nitrogen/Hydrogen Content Test (ONH Analyzer)
2
Dimensional Testing
Three coordinate CMM measurement (accuracy level up to ± 0.005mm)
Ultrasonic UT testing (detection of internal cracks and inclusions)
Surface roughness test
Vickers hardness HV test
3
Specialized testing for target materials, crucibles, and high-end components
Density detection - Archimedes method
Internal stress testing (processing stress/residual stress)
Microstructure analysis (SEM)
Process Quality Management
We strictly follow the manufacturing process for segmented quality control, allowing customers to see that 'every step is tested and every link is traceable'.
1. Raw material incoming inspection
Verify supplier composition report
Batch filing+coding traceability system
Sampling re inspection ensures consistency with specifications
2. Smelting and ingot preparation
Vacuum Melting Furnace (VIM)
Multiple melting processes to improve material uniformity
Fully record the melting curve and parameters
3. Forming processing (forging/rolling/machining)
Hot forging → Hot rolling → Cold rolling
Strictly control the rolling ratio to ensure a dense structure
Perform hardness and mechanical property testing on each batch
4. Deep processing inspection
Target material: flatness, grain size, density
Crucible: wall thickness tolerance controllable to ± 0.02mm
Processed parts: Comparison between CNC dimension inspection records and drawings
5. Factory inspection (100% full inspection)
appearance inspection
Ingredient Report (COA)
Dimensional Inspection Report
Non destructive testing report (UT/RT optional)
Each document can be attached with the goods to ensure risk-free procurement for customers.
