AI-Powered supplier vetting

SummaryBaoji Titanium Progress New Technology Co., Ltd. is identified as a Chinese manufacturer/factory specializing in titanium and titanium-alloy products. The supplier reports ISO 9001 and ISO 14001 certifications, two production lines, fewer than five R&D engineers, and fewer than five quality-control staff. It serves a broad range of export markets and accepts several international trade and payment terms, but its export-start date is listed as December 17, 2025, indicating limited documented export history. Production is reported below the stated annual output threshold, with off-peak lead times within 15 working days and peak fulfillment of one month. The provided information does not establish after-sales service performance, financial credibility, customization execution, or specific customer cases.

Supplier typeThe supplier is explicitly classified as a Manufacturer/Factory and is described as specializing in the research, development, production, and sales of titanium and titanium-alloy products. This supports direct manufacturing status rather than a trading-only profile.

CertificationsThe supplier reports ISO 9001 and ISO 14001 certification and states that it can meet special industry standards such as AMS and NACE. These certifications and stated standards capability provide explicit evidence of formal quality and environmental management, although certification scope is not specified.

R&D capabilityThe company is described as a high-tech enterprise engaged in research and development of titanium and titanium-alloy products, and it reports fewer than five R&D engineers. This demonstrates an R&D function, but the limited documented engineering scale and absence of patent or new-product evidence prevent a stronger assessment.

Production capacityThe supplier reports two production lines, full-process quality monitoring, and order fulfillment within 15 working days off-peak and one month during peak periods. However, annual output is reported below the stated threshold and the available data does not quantify capacity, so the evidence supports operational production capability but not large-scale capacity.

Product Q&A

Q:What is the difference between Grade 2 (TA2) and Grade 5 (TC4) titanium?

Grade 2 (TA2) is pure titanium with excellent corrosion resistance & good formability, ideal for marine, chemical, and general industrial use. Grade 5 (TC4 / Ti-6Al-4V) is a high-strength aerospace alloy with 900+ MPa tensile strength, heat treatable, best for high-stress, weight-critical applications.

Q:Are these screws comparable to steel grades?

Yes. TC4 (Ti-6Al-4V) performance equals or exceeds 12.9-grade alloy steel at ~57% the weight. TA2 is similar to 8.8-grade steel in strength but far more corrosion-resistant and 40% lighter.

Q:What surface treatments do you offer?

We provide plain (bright) finish and professional hard anodization in blue, gold, black, purple, rainbow, and ice crystal patterns. All anodized coatings are wear-resistant, color-stable, and non-conductive.

Q:What certifications and quality checks do you provide?

All products are manufactured under ISO 9001. We supply Material Test Reports (MTR), hardness reports, dimensional inspection reports, and salt spray test reports. Third-party testing (SGS, BV) is available upon request.
