Import Best Quality Calcium Metal — Buy in Bulk from Supplier in South Africa

Calcium metal from Foshan Mafrika Stock And Supplies is supplied as a silvery-white reactive metal available in powder, lump and granulate forms, with a density of 1.54 g/cm³, melting point of 850 °C and boiling point of 1440 °C (lit.). The CAS number is 7440-70-2. It is harder and heavier than alkali metals such as lithium, sodium and potassium, and it oxidises rapidly in air to form a protective oxide film. When heated, it burns with a characteristic brick-red flame. The supplier sources this material from South Africa and trades as an imported-stock entity with harbour-tier trust standing.

The metal reacts slowly with cold water and vigorously with hot water, liberating hydrogen. It combines readily with halogens, sulphur and nitrogen. In industrial practice, calcium of this grade is typically supplied with controlled particle size distribution for specific applications, though the exact sieve analysis should be requested from the supplier. Standard commercial grades range from 98% to 99.5% purity, with iron, nitrogen and magnesium as common trace elements. Packaging for reactive metals of this class typically involves argon-filled sealed steel drums or vacuum-sealed aluminium laminate bags to prevent surface oxidation during ocean freight from South African ports.

Primary buyers are steel mills and foundries that convert calcium into calcium iron wire or pure calcium wire for ladle refining, where it functions as a desulphuriser, deoxidiser and fluidity improver in high-grade steel production. It also serves as a dehydrating agent in anhydrous alcohol manufacture and as a desulphurising agent in petroleum refining. Metallurgical and chemical importers should confirm with Foshan Mafrika Stock And Supplies the exact purity level, particle size distribution, packaging specification and any available mill test certificates before placing an order.

Foshan Mafrika Stock And Supplies operates as an imported-stock supplier with harbour-tier verification status. The company sources calcium metal from South Africa and holds inventory for B2B distribution. No response rate data is available, and average response time is unrecorded, so buyers should allow extra time for initial contact and confirmation of stock availability. The supplier's name suggests cross-border trading operations between China (Foshan) and Africa, though the exact corporate structure, warehouse locations and stocking capacity are not stated in the available profile.

The listing provides product-level technical data but does not disclose factory audit reports, ISO certifications, export licences or quality management accreditations. Buyers should request documentation directly. The supplier handles a single-product focus in this listing (calcium metal in multiple forms), which may indicate specialised trading in reactive metals rather than broad chemical distribution. Any claims about production capacity, annual turnover, employee count or major client relationships should be treated as unverified unless the supplier provides written proof.
