Iron Ball | Complete Product Parameters and Function Description (Export-Specific Full Version)

I. Product Introduction

Iron balls, also known as solid iron beads or industrial iron balls, are basic general-purpose industrial accessories made from high-purity pig iron and low-carbon iron materials. They are processed through standardized processes such as forging, precision polishing, roundness calibration, surface polishing, burr removal, and anti-rust treatment. The products have a dense overall structure, regular spherical shape, uniform size, no hollows, no sand holes, and no cracks. They feature high density, stable weight, strong plasticity, excellent cost-performance, and wide applicability. Strictly manufactured in accordance with industry standards, the batches of products have high consistency and strong interchangeability. They can be subjected to secondary surface treatments such as galvanizing, chrome plating, blackening, and anti-rust oil as per requirements. As basic general-purpose accessories for weighting, limiting, rolling, and filling, iron balls are in high demand in the fields of hardware and light industry, toy manufacturing, fitness equipment, general machinery, and daily accessories. They are well-suited for global mid-to-low-end conventional industrial and civil markets, and are the main products with high cost-performance for export.
