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 A99 / A4N6 (99.996% – 99.9985%) aluminum a vital material for high-performance industrial and metallurgical applications. While this grade serves broader industrial needs than ultra-high purity versions, its performance remains sensitive to trace elements. Total regulated impurities, including Lithium, Beryllium, Titanium, and others, are strictly maintained at no more than 0.0015 wt.% to ensure the metal meets the rigorous standards of GOST 11069-2001 and international specifications.
Product Form and Handling
High-purity aluminum of this grade is typically supplied as trapezoidal ingots weighing 16 kg. These ingots are produced using the double electrolysis method in a protective atmosphere, which ensures a stable chemical composition and minimizes the inclusion of gases and non-metallic impurities.
For industrial-scale logistics, the metal is organized into 1 metric ton pallets. To maintain the integrity of the material, pallets are securely wrapped to protect against environmental exposure during transit. Following standard logistics protocols ensures the material remains pristine until the moment of discharge at the manufacturing site.
Why Purity Matters
In modern manufacturing, the transition from standard to high-purity aluminum is often driven by the need for predictable material behavior in complex casting and alloying processes. Aluminum with a purity of 99.996% – 99.9985% provides the necessary reliability for the aerospace, transportation, and electrical engineering sectors.
The use of A99 / A4N6 grade aluminum minimizes the risk of structural defects in finished components, which is critical for safety-sensitive industries. In competitive markets with high production targets, the availability of large, consistent batches helps speed up manufacturing workflows by reducing the need for constant adjustments to compensate for impurity variations. Registered under HS Code 7601 10 00 00, this material is the primary choice for unalloyed, unwrought aluminum across metallurgy, construction, and the food packaging industry.
Applications of High Purity Aluminum (A99, A4N6)
High-purity aluminum, defined by its chemical purity of 99.996% – 99.9985%, is a foundational material for advanced metallurgy and high-performance industrial applications. While optimized for larger-scale production than 5N or 6N grades, it offers the essential low density, superior electrical conductivity, and corrosion resistance required for rigorous engineering standards. Produced via double electrolysis in a protective atmosphere according to GOST 11069-2001, A99/A4N6 aluminum is indispensable in:
