1、 Key points of customized parameter design

1. Purity and specification adaptation

Purity requirement: High end industrial fields require the selection of high-purity niobium plate targets (Nb1, Nb2 grades) with a purity of ≥ 99.95% and impurity content of ≤ 0.05% to ensure sputtering performance and corrosion resistance.

Size range: Common thickness is 0.5-65mm, diameter is 5-245mm, and non-standard shaped parts customization is supported.

2. Surface treatment and precision control

The surface roughness of the target material for sputtering coating should be ≤ Ra 0.8 μ m, and CNC precision machining can achieve a tolerance of ± 0.05mm.

Medical target materials require additional passivation or silver doping coating treatment to reduce the risk of biological rejection reactions.

2、 Quality certification system

Industrial grade: Complies with ASTM B393 standard, requires component testing report and grain size analysis.

Special scenarios: Nuclear power requires neutron absorption cross-section test data, while aerospace requires compliance with AMS 7852 standards.

3、 Cost optimization strategy

Process selection:

Rolling process has a 15% lower cost than forging, but its mechanical properties are slightly inferior, making it suitable for non load bearing components.

Additive manufacturing reduces material loss, and the processing cost of complex structured target materials can be reduced by 30%.

5、 Risk avoidance suggestions

When signing the technical agreement, specify the acceptance criteria (such as purity retesting, dimensional tolerances, and allowable range of surface defects).

Prioritize selecting manufacturers that provide waste target recycling services to reduce long-term usage costs.
