Key Industrial Applications
Essential Use in Metallurgy
Antimony is an indispensable hardening agent for lead and tin-based alloys. It adds vital structural integrity to lead-acid battery plates, increasing mechanical strength, electrical conductivity, and service life. It also maximises wear resistance in Babbitt bearing alloys and hardens pewter formulations.
Flame Retardant Synergists
When converted into antimony trioxide, this material acts as a critical flame retardant synergist in plastics, rubber, and synthetic textiles, meeting strict commercial fire safety standards.
Global Logistics & Regulatory Compliance
While we primarily serve the domestic UK manufacturing sector, DKL Metals operates a robust international freight network providing efficient global sea and air shipping. All shipments arrive with full certificate of analysis (CoA) documentation, Safety Data Sheets (SDS), and comply strictly with UK REACH and European environmental standards.
Frequently Asked Questions
What is the difference between 99.65% and 99.9% antimony purity?+
Our 99.65% minimum antimony ingots are optimised for high-volume industrial metallurgy, alloy hardening, and flame-retardant production. The ultra-pure 99.90% grade is refined specifically for precision electronics, semiconductor doping, and high-specification chemical compounding where trace elements must be strictly minimised.
How is the purity of the antimony verified?+
Every single batch of antimony ingots undergoes rigorous spectrographic analysis. We issue a formal Certificate of Analysis (CoA) with every delivery detailing exact purity percentages and trace element levels.
What are the safety regulations for handling industrial antimony in the UK?+
Antimony products supplied by DKL Metals comply fully with UK REACH and European environmental standards. Every shipment is provided with a comprehensive Safety Data Sheet (SDS) detailing local exposure limits, recommended personal protective equipment (PPE), and safe workplace handling practices.
