Yes, trial orders are available for most products, excluding custom-engineered alloys. Please select the “Trial quantity required” option when submitting your RFQ form.
Lead times vary depending on the type of order. Below is an overview of typical processing and delivery times for our main order categories:
- Trial batch orders are typically dispatched within 5 business days from the date of payment receipt.
- Ultra high-purity metals purchase orders are fulfilled within 7–14 business days from the date of advance payment under the main agreement, depending on quantity and destination.
- Custom alloy wire manufacturing orders include a development phase and are scheduled individually based on product complexity, specification, and volume.
Lead time for each custom alloy wire contract is determined jointly with the client and includes both production and quality assurance stages.
Yes, we can arrange logistics and deliver to any international airport specified by the buyer.
Our order processing follows a structured and transparent workflow aligned with Incoterms 2020 practices:
- Client: submits an LOI (Letter of Intent) or RFQ form to Pure Metals.
- Jointly: we clarify and confirm all technical and commercial details of the LOI/RFQ.
- Pure Metals: issues an FCO (Full Corporate Offer). We intentionally skip SCO (Soft Corporate Offer) to streamline the process.
- Client: confirms the FCO and provides proof of funds (BCL or equivalent banking document).
- Optionally: a trial quantity shipment may be arranged under an accelerated procedure, based on a simplified standalone agreement. Upon receipt, the client confirms that the product quality meets the required specifications.
- Pure Metals: drafts the contract and coordinates revisions with the client.
- Both parties: sign the final contract.
- Client: makes a partial advance payment — typically 25% of the total value of the initial product batch.
- Pure Metals: dispatches the goods and provides the transport documentation to the client.
- Client: completes final payment and receives the goods at the destination in accordance with the transport documentation and agreed delivery terms.
Absolutely. Once your RFQ or LOI is agreed upon and the FCO is signed, we’d be happy to arrange a visit to one of our warehouses that best suits your order specifics. If needed, we can also organize self-pickup of your order from the warehouse under the appropriate Incoterms 2020, making the process as smooth and convenient for you as possible.
Yes, we assist with all necessary documentation to help streamline logistics, compliance, and customs clearance — regardless of the products combination or technical specifications in your order.
Yes, every delivery includes a lab certificate to verify product purity and ensure batch-to-batch consistency.

Ultra High Purity Aluminum: Material Profile
Aluminum is a lightweight Group 13 metal with an electron configuration of [Ne] 3s^2 3p^1, which accounts for its high chemical activity and the ability to form a durable protective oxide film. It melts at 660.3°C, boils at 2470°C, and has a density of approximately 2.70 g/cm³. Among structural and conductive materials, aluminum stands out for its excellent specific electrical conductivity and high thermal conductivity (0.57 cal/cm·°C·s).
These characteristics, combined with exceptional ductility and corrosion resistance, make A6N (99.9999%) aluminum indispensable in the fields of nanotechnology and quantum computing. However, the physical properties of the metal at this level of purity are extremely sensitive to trace impurities. Even the presence of trace amounts of elements such as iron, silicon, copper, or magnesium at the ppb (parts per billion) level can distort the crystal lattice, reducing the material’s radiation resistance and electrical conductivity at ultra-low temperatures. Among structural and conductive materials, aluminum stands out for its excellent specific electrical conductivity and high thermal conductivity (0.57 cal/cm·°C·s).
Product Form and Handling
Extreme-purity aluminum is typically supplied as semi-cylindrical or round ingots — compact, silvery-white blocks weighing from 2.5 to 6 kg with a mirror-like surface finish. Unlike standard industrial ingots, A6N ingots are produced through multiple zone refining, ensuring near-perfect structural homogeneity.
Each ingot undergoes individual preparation: it is hermetically sealed in a polyethylene or inert protective wrap. This is necessary to eliminate even the slightest contact with the environment, prevent surface adsorption of gases, and maintain the “six nines” purity during transit and storage in high-tech warehouse facilities.
Why Purity Matters
Modern industry demands not just high-quality raw materials, but substances with predictable behavior at the atomic level. A6N aluminum enables stable results in magnetron sputtering (PVD) processes and during single crystal growth. The use of ultra-pure aluminum minimizes the risk of “hot spots” and defects in thin films of microcircuits, which is critical for the production of next-generation processors and aerospace components. In an environment of strict requirements for product yields, purity at the 99.9999% level becomes the guarantee of efficiency for the entire production chain.
Applications of Ultra High-Purity Aluminum (A6N)
Ultra high-purity aluminum, defined by its extraordinary 99.9999% (6N) purity level, is a critical material for industries where the slightest atomic-level impurity can compromise performance. Its combination of low density, high thermal and electrical conductivity, and exceptional corrosion resistance makes it superior to lower-grade alternatives in high-tech environments. A6N aluminum is indispensable in:
