Cornmax Technology — Verified Supplier
About Cornmax Technology - Titanium Tube Supplier in China
Cornmax Technology is located in China and currently lists nine active products on its catalogue. All items fall under the broader titanium metal family and are classified under HS Chapter 81, specifically codes 8108.20 for sheet, bar, rod and plate, and 8108.90 for pipe, tube, wire and specialized components. The catalogue includes a Gr2 ASTM B337 titanium pipe, a Gr2 ASTM B338 tube, a medical‑use Grade 5 titanium wire, and a customized Grade 1 titanium electrode with mixed noble metal oxide coating. Additional products cover ASTM F136 Grade 5 titanium sheet, bar, rod and plate, as well as CNC machining services for titanium alloys and pure grades. Each entry specifies the applicable ASTM grade and material composition, ranging from commercially pure Grade 2 (Ti‑99.2 %) to the alloy Ti‑6Al‑4V (Grade 5).
The pipe and tube items share HS code 8108.90 and are described as commercially pure titanium Grade 2, conforming to ASTM B337 and B338 standards for dimensional tolerance and corrosion resistance. The medical‑use wire is listed under the same HS code but uses Grade 5 alloy (Ti‑6Al‑4V) which meets ASTM B348 requirements for tensile strength and biocompatibility. Electrode products also carry HS code 8108.90 and combine a Grade 1 titanium substrate with a coating of iridium, ruthenium, tantalum and platinum oxides, a composition common for inert anodes in electrolytic applications. Sheet, bar, rod and plate entries fall under HS code 8108.20, reflecting their classification as flat or shaped titanium products for aerospace, chemical processing and medical device manufacturing. The CNC processing service is likewise coded 8108.90 and indicates capability to machine both Ti‑6Al‑4V alloy and pure grades 1 through 4 to customer specifications.
Product Range and Specialties of Cornmax Technology
Cornmax’s catalogue presents a focused selection of titanium semi‑finished products, primarily in commercially pure Grade 1‑2 and the alloy Grade 5 (Ti‑6Al‑4V). In the pipe and tube segment, ASTM B337 and B338 define tolerances of ±0.2 mm for outer diameter and wall thickness, with typical wall thicknesses ranging from 0.5 mm to 5 mm. The Grade 5 wire, intended for medical use, is commonly supplied in coils of 500 m to 1 km and meets ASTM B348 specifications of minimum tensile strength 950 MPa and elongation above 10 %. Titanium sheets and plates under ASTM F136 are usually offered in thicknesses from 1 mm to 30 mm, with surface finish grades such as mill finish or polished to 0.8 µm Ra. Bars and rods in the same alloy are typically delivered in lengths of 2 m to 6 m, with diameters from 10 mm up to 200 mm, matching aerospace and high‑pressure valve standards.
The CNC processing service lists capability to machine both Ti‑6Al‑4V and pure grades 1‑4, which aligns with industry practice of using high‑speed steel or carbide tooling to achieve tolerances of ±0.05 mm. Typical output includes precision components such as aerospace brackets, medical implants and chemical reactor parts, often finished to surface roughness of 1.6 µm Ra or better. Customers usually request production in 20‑ft or 40‑ft containers, with protective packaging such as anti‑corrosion film and wooden pallets to prevent surface damage.
Trade and Export Information - Cornmax Technology
China is a major global exporter of titanium products, and shipments classified under HS 8108.20 and 8108.90 are routinely directed to Europe, North America and Southeast Asia for aerospace, medical device and chemical processing applications. Importing countries often require material test reports (MTR), mill test certificates (MTC) and compliance with ASTM or ISO standards, with ISO 9001 quality management certification being a common prerequisite for bulk orders. Customs authorities in the destination markets may request additional documentation such as a certificate of origin and, for aerospace‑grade material, an EN 9100 or AS 9100 certificate. Typical packaging for titanium sheets, plates and bars involves double‑layered wooden crates, bubble‑wrap protection and moisture‑resistant pallets, allowing safe transport in 20‑ft or 40‑ft containers under CIF or FOB terms. Export controls for titanium alloy items are generally limited, but high‑purity grades used in defense applications may be subject to end‑use verification under the Wassenaar Arrangement.
Lead times for bulk titanium products from Chinese mills range from 30 to 60 days, depending on alloy grade, machining requirements and container availability. Buyers frequently arrange pre‑shipment inspection by agencies such as SGS or Bureau Veritas to verify grade, dimensions and surface condition against the agreed specifications.
Sourcing from Cornmax Technology - Buyer Guidance
When sourcing titanium from Cornmax, buyers should request the latest material test report and mill test certificate confirming the exact ASTM grade (e.g., B337, F136) and chemical composition limits. For medical‑use wire or aerospace sheet, a certificate of compliance with ASTM B348 or F136, together with a declaration of compliance to ISO 13485 (medical) or AS 9100 (aerospace), is advisable. Samples of a representative batch should be inspected for dimensional tolerance, surface finish (Ra value) and mechanical properties such as tensile strength and elongation. Verification of the HS code alignment (8108.20 for flat products, 8108.90 for pipes, tubes and electrodes) helps ensure correct tariff treatment and customs clearance.
Buyers should confirm the minimum order quantity, which for bulk sheet, plate or bar is typically one standard container (≈20 tons) unless a smaller lot is arranged through the CNC service. Clarify packaging details - anti‑corrosion film, wooden pallets, and moisture‑proof wrapping - to avoid surface oxidation during sea transit. Establish the preferred Incoterm (FOB Shanghai or CIF destination) and request a production schedule that includes any heat‑treatment or surface‑coating steps required for the final application.
Frequently Asked Questions About Cornmax Technology
What titanium grades does Cornmax Technology offer in its catalogue?
It lists commercially pure Grade 1 and Grade 2 (ASTM B337/B338) and the alloy Grade 5 Ti‑6Al‑4V (ASTM F136/B348) across pipe, tube, wire, sheet, bar, rod, plate and CNC‑machined parts.
Which HS codes are applicable to the products listed by Cornmax?
Products that are pipes, tubes, wires, electrodes and CNC‑processed components use HS 8108.90, while sheet, bar, rod and plate items are classified under HS 8108.20.
What standards govern the titanium pipe and tube supplied by Cornmax?
