Pure metals and pre-alloys in granules, shot and drops — engineered for jewellery, soldering, brazing and micro-casting applications.
MEPOSO manufactures pure metals and pre-alloys in granule, shot and drop form across numerous alloy configurations. Our granulation process delivers uniform particle geometry, tightly controlled size distribution and consistent chemical composition from batch to batch.
The product range encompasses brass drops (CuZn) in six standard grades, copper-phosphorus drops (CuP) for brazing and deoxidation, and copper-nickel drops (CuNi) for specialised alloying. Custom compositions and grain sizes are available on request.
MEPOSO offers a comprehensive range of brass drops covering zinc contents from 10% to 45%, plus a nickel-silver variant. Available as shot, grain, granules and metal pellets, these alloys are widely used in jewellery manufacturing, brazing and micro-casting processes.
Grain size is produced to customer specification. All grades feature consistent composition and clean surface finish for reliable melting behaviour.
| Grade | Composition | Available Forms |
|---|---|---|
| BRASS 700 | Cu bal – Zn 30% | Shot, Grain, Granules, Metal Pellets |
| BRASS 670 | Cu bal – Zn 33% | Shot, Grain, Granules, Metal Pellets |
| BRASS 200 | Cu bal – Zn 20% | Shot, Grain, Granules, Metal Pellets |
| BRASS 100 | Cu bal – Zn 10% | Shot, Grain, Granules, Metal Pellets |
| BRASS 550 | Cu bal – Zn 45% | Shot, Grain, Granules, Metal Pellets |
| BRASS NS | Cu bal – Zn 18% – Ni 18% | Shot, Grain, Granules, Metal Pellets |
CUP-series copper phosphorus drops are used extensively as a deoxidant and alloying agent. Available with phosphorus content ranging from 6% to 15%, these drops provide precise phosphorus additions during melting and brazing operations.
Supplied as shot, grain and granules in three standard size fractions: <3 mm, 3–6 mm and 5–15 mm. The controlled granulometry ensures predictable dissolution and consistent alloy composition in the final product.
| Grade | Composition | Standard Sizes | Primary Use |
|---|---|---|---|
| CUP | Cu bal – P 6 to 15% | <3 mm, 3–6 mm, 5–15 mm | Deoxidant & alloying agent |
CUPRONI copper-nickel drops are available with nickel content from 10% to 20%. Supplied as shot, grain and granules, these pre-alloy drops enable accurate nickel additions for alloy production, ensuring homogeneous distribution in the melt.
Grain size is produced to customer specification. CUPRONI drops are widely used in the production of cupronickel alloys for marine, electrical and coinage applications.
| Grade | Composition | Available Forms |
|---|---|---|
| CUPRONI | Cu bal – Ni 10 to 20% | Shot, Grain, Granules |
