Import Ball Chain — Buy in Bulk from Supplier in China

China Yoomay Decorative Chain Co.,ltd. produces ball chain in sizes from 1.5 mm to 15 mm diameter, using brass, iron, or stainless steel substrates depending on application requirements. The ball chain construction consists of spherical metal beads connected by short wire links or formed from coiled wire with integral ball swaging, creating a flexible yet linear chain structure. Surface finish is described as smooth to prevent snagging, though specific finish types (polished, plated, or coated) are not detailed. The supplier positions this product across industrial and decorative segments, from keychain hardware to lighting fixture suspension.

Brass ball chain offers corrosion resistance and machinability for decorative and electrical applications, with typical alloy composition CuZn30 to CuZn40. Iron ball chain provides lower material cost for high-volume applications where corrosion protection is secondary, typically requiring zinc or nickel plating for indoor use. Stainless steel grades 304 or 316 deliver maximum corrosion resistance for marine, food processing, or outdoor architectural applications, though the supplier does not specify exact grades. Ball diameter tolerance and link wire diameter determine breaking strength; standard industry practice for decorative ball chain tolerates plus or minus 0.1 mm on ball diameter, while precision instrument chain demands tighter control. The smooth finish referenced typically results from barrel polishing or centrifugal finishing after forming.

Buyers span automotive trim suppliers, fashion accessory manufacturers, lighting fixture producers, and hardware distributors serving retail and commercial channels. The 1.5 mm to 2.4 mm sizes suit jewellery, ID badge lanyards, and keychains; mid-range 3.2 mm to 6.0 mm serves pull chains for fans and lighting; larger 8 mm to 15 mm accommodates industrial retaining and decorative architectural applications. The supplier mentions CIF and FOB shipping terms, with滞期费 buyers should confirm port of shipment and whether Yiwu, Ningbo, or Shanghai serves as the load port. No MOQ is stated in the available data, and buyers must confirm minimums, coil or cut-length packaging, and whether custom plating colours are offered.
