Gold target price manufacturers

When selecting gold targets (sputtering targets), the most critical factor is purity, typically requiring 99.99% (4N) or 99.999% (5N) levels to ensure film conductivity and color consistency. You must also specify the density, which should be >99% of the theoretical density to prevent 'spitting' or micro-particles during the deposition process. Additionally, confirm the grain size uniformity; a fine, homogenous grain structure ensures a stable erosion rate and longer target life.

Buyers must ensure suppliers provide a Certificate of Analysis (COA) for every batch, detailing trace element impurities via GDMS or ICP-OES testing. For international trade, compliance with Conflict Minerals regulations (e.g., Dodd-Frank Act) is essential to prove the gold is ethically sourced. Furthermore, ensure the manufacturer follows ISO 9001 quality management systems to guarantee dimensional tolerances (usually ±0.1mm) and surface roughness (Ra < 0.8μm).

Gold targets are primarily used in Physical Vapor Deposition (PVD) for semiconductor metallization, MEMS fabrication, and high-end decorative coatings (e.g., luxury watches and jewelry). Functional requirements include excellent adhesion to the substrate and low electrical resistivity. For industrial applications, the target is often indium-bonded to an oxygen-free copper (OFC) backing plate to facilitate efficient cooling during high-power sputtering.

Since gold is a precious metal, the price is heavily influenced by the real-time London Bullion Market Association (LBMA) spot price. To optimize costs, look for suppliers who offer refining and recycling programs, where spent targets (skeletons) can be exchanged for credit. Evaluate the utilization rate of the target design; for example, rotary targets often offer higher material utilization than planar targets, reducing the frequency of expensive replacements.

Given the high unit value, use secure payment methods such as Letters of Credit (L/C) or Escrow services provided by reputable platforms like Made-in-China.com. Always lock in the gold surcharge at the time of the Proforma Invoice to avoid price volatility during the production lead time.

Gold targets should be shipped via insured express couriers (e.g., FedEx, DHL, or UPS) with high-value cargo handling. Ensure the product is vacuum-sealed in double-layer plastic bags to prevent oxidation or contamination and packed in discreet, tamper-evident wooden crates to minimize theft risks during transit.

Negotiate a clear buy-back or recycling agreement before placing the order. Professional suppliers should offer a transparent credit system based on the weight of the remaining gold scrap, minus a small processing/refining fee. This can significantly lower the Total Cost of Ownership (TCO) for long-term projects.

You must provide a detailed Commercial Invoice specifying the gold weight and purity, a Packing List, and the COA. Ensure the HS Code (typically 7108.13) is accurate to determine the correct import duties and VAT. Some countries may require an import license for precious metals, so verify local regulations before the shipment departs.
