Pure Tin Bars & Sticks
Standardised high-purity bars and sticks, available also in chunk form
Industrial Applications & Capabilities
Electroplating & Printed Circuit Boards (PCBs) +
Pure tin acts as a critical, high-purity etch resist for PCBs, protecting underlying copper traces during manufacturing. DKL supplies anodes in high-purity ingot, bar, or granule forms to ensure consistent plating performance, prevent secondary anode sludge formation, and allow for completely uniform anode dissolution within active electroplating baths.
Hot Dip Tinning Processes +
Utilised to apply protective, corrosion-resistant metallic coatings directly to steel surfaces. This continuous process involves a molten tin immersion phase that ensures superior surface adhesion and lifetime oxidation protection, ideal for critical electronic components and heavy industrial steel processing.
High-Performance Solders & Electronics +
Supplying high-purity tin raw materials, which form the direct alloy foundation for modern, lead-free soldering systems used throughout the automotive and consumer electronics sectors to meet strict international environmental and performance regulations.
Specialty Float Glass & Chemical Uses +
Pure tin is essential in flat float glass production to create completely level liquid metal beds for forming flawless glass sheets. It is additionally utilised for manufacturing high-quality chemical catalysts and specialty industrial metal products.

Frequently Asked Questions
What purity grades are available for DKL tin anodes? +
DKL Metals supplies high-purity tin anodes with a minimum certification of “Three Nines Tin” (99.9% Sn purity). Higher premium-tier industrial grades, including Four Nines (99.99% Sn) and Five Nines (99.999% Sn), are available upon order request to meet strict military, aerospace, or electronic component specifications. For manufacturing foundries and bulk melting applications, you can also view our High Grade Tin Ingot supply options.
What profiles are available in the pure tin range? +
We supply pure tin anodes across a versatile range of profiles, specifically Ovals, Hemispheres, Flat Rolled Anodes, and Granules. Standardised Pure Tin Bars and sticks are manufactured directly in-house at our own UK facility to fit your standard warehouse inventory configurations.
How are pure tin products packaged for industrial distribution? +
Our distribution model dictates that standard pure tin bars and sticks are packed in 20kg cartons. For bulk granular formats, all pure tin pellets, granules, and chunked bars are supplied securely inside 20kg bins to preserve material integrity during industrial transport.
Do your pure tin products comply with international standards? +
Yes. All DKL pure tin products match specific international, national, or custom internal corporate standards. Our manufacturing lines for bars and sticks operate under a rigorous quality framework certified to ISO 9001:2015 and environmental standard ISO 14001:2015.
