Import 3% Boron Aluminium Alloy Alb3 — Buy in Bulk from Supplier in China

3% boron aluminium alloy ALB3 is a grain-refining master alloy supplied in waffle ingot form, with the boron content held at 3% by weight to optimise nucleation potency during aluminium casting. The alloy's composition includes silicon, iron and copper as residual or intentional alloying elements, though exact limits for these trace elements are not stated in the listing and should be verified against ASTM B233 or the buyer's internal melt specification. Waffle ingot geometry, with its cast surface area and interlocking shape, allows rapid dissolution in molten aluminium and reduces the risk of boride cluster formation that can occur with lump or shot forms.

In typical master alloy practice, boron is introduced to form discrete AlB2 and AlB12 phases that act as heterogeneous nucleation sites for primary aluminium grains, refining cast grain size from hundreds of microns down to tens of microns. The 3% boron level positions this alloy within the standard range for aluminium-boron master alloys used in electrical conductor production, where fine grain size improves conductivity and drawability. Buyers should confirm whether this grade is titanium-free or low-titanium, as titanium contents above 0.03% can poison boron grain refinement by forming stable TiB2 that competes with AlB2 for nucleation sites.

Primary applications include electrical wire and cable conductor manufacturing, where fine equiaxed grain structure prevents surface cracking during rod breakdown and drawing to fine wire. The alloy also serves foundries producing aerospace and automotive structural castings requiring uniform mechanical properties and reduced porosity. For importers, this listing originates from Qinhuangdao in Hebei Province, a northern Chinese industrial hub with established aluminium smelting and downstream processing infrastructure. Trade terms, MOQ and lead time are not specified and must be confirmed directly with the supplier, along with certification to EN 573-3 or equivalent national standards.

Qinhuangdao Aolaide Aluminum Industry Technology Co., Ltd. is located at No.27 Heilongjiang West Road, Qinhuangdao 066004, Hebei Province, China. The supplier holds an 'imported' tier designation with a 'harbor' trust level, though the response rate is recorded at 0.00% with zero average response hours, indicating no engagement data is available through the platform. The company operates within China's established aluminium industrial corridor in Hebei, near the Port of Qinhuangdao, which provides logistical access for bulk metal shipments.

The listing provides minimal verified company-level information beyond the registered address and tier indicators. No factory size, annual output, number of employees, year of establishment, or specific client references are stated. The source description contains generic marketing content that should not be relied upon as verified fact. Buyers should conduct independent due diligence, request a company profile, and verify business registration through official Chinese channels before committing to orders. The absence of response history suggests direct contact will be necessary to assess communication reliability and technical competence.
