Import Bronze Powder — Buy in Bulk from Supplier in China

Xingtai Tianao Import And Export Trading Co., Ltd. lists bronze powder at 99.9% purity with a 200-300 mesh specification and a density of 8.9. The stated melting point is 950 degrees Celsius, positioning the material for elevated-temperature applications including die-casting and powder metallurgy. The 200-300 mesh range converts to approximately 74-44 microns, a relatively coarse fraction suited to pressing and sintering rather than fine pigment work. No information on alloy composition, oxygen content, or tap density is provided, so buyers must supplement the published data with direct technical enquiry.

The 99.9% purity claim requires careful interpretation. In bronze powder terminology, this could mean 99.9% metal content with trace non-metallics, or it could refer to the copper fraction before tin addition. Standard bronze is not 99.9% pure copper-tin alloy, as the tin content of 10% would reduce copper to approximately 90%. Buyers should clarify whether the figure refers to total metallic purity, copper purity, or absence of specific contaminants. The 200-300 mesh size is typical for powder metallurgy feedstock, where good flow and packing density are required. Apparent density and Hall flow rate, standard metrics for press-and-sinter operations, are not stated and should be requested.

Target applications from the supplier include die-casting, powder metallurgy, surface coatings, automotive, and electronics sectors. The 950 degrees Celsius melting point sits below pure copper at 1085 degrees Celsius, consistent with tin bronze phase diagrams where liquidus falls with increasing tin. For powder metallurgy, this lower melting point can be advantageous in sintering cycles. The supplier mentions FOB and CIF Incoterms, with flexible MOQ, though no specific quantity is published. Payment via letter of credit or telegraphic transfer is indicated. Response metrics are unavailable, so initial contact should test communication speed and technical competence before proceeding to sample evaluation.

Xingtai Tianao Import And Export Trading Co., Ltd. is registered at Room 402, Unit 2, 5th Building Procuratorate, Quannan West Road, Qiaoxi District, Xingtai, Hebei Province, postal code 054000. The company holds imported supplier tier and harbour trust classification. Response rate and average response hours are both recorded as zero, indicating no platform-mediated communication history. The address is a commercial office rather than an industrial site, suggesting the company may operate as a trading intermediary rather than a primary manufacturer.

The listing does not disclose manufacturing assets, workforce size, annual turnover, or years in operation. No specific ISO certificate numbers, SGS reports, or laboratory accreditations are provided for independent verification. The description frames the company as an import and export trading entity, which reinforces the possibility that production is outsourced. Buyers should request a factory audit, manufacturing licence, and direct video evidence of production lines before assuming vertical integration. Due diligence should include verification of the legal entity registration with the Hebei Administration for Market Regulation.
