Can you supply custom grades or particle size distributions?
Yes. MEPOSO can discuss chemistry, morphology, particle size and apparent density targets according to the industrial application and production process.
MEPOSO manufactures Pre-alloys & Granules for jewellery, soldering, brazing and micro-casting.
MEPOSO supplies Pre-alloys & Granules for jewellery, soldering, brazing and micro-casting, with technical support for industrial qualification and repeatable production.
The range is designed for B2B buyers looking for stable quality, controlled particle characteristics and export-oriented supply.
MEPOSO pre-alloys support soldering routes, alloying additions and contact-material manufacturing with controlled copper phosphorus, brass and copper nickel granules.
MEPOSO offers brass drops with zinc content from 10% to 45%, plus a nickel-silver variant, for jewellery manufacturing, brazing and micro-casting.
The range is available as shot, grain, granules and metal pellets, with customer-oriented sizing and stable alloy composition.
| 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 copper phosphorus drops are used as a deoxidant and alloying agent, with phosphorus content from 6% to 15% for melting and brazing processes.
Supplied as shot, grain and granules in standard size fractions, they support predictable dissolution and controlled alloy composition.
| 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% for accurate alloy additions and homogeneous melt distribution.
Supplied as shot, grain and granules, they are used for cupronickel alloy production in marine, electrical and coinage applications.
| Grade | Composition | Available Forms |
|---|---|---|
| CUPRONI | Cu bal – Ni 10 to 20% | Shot, Grain, Granules |
Typical applications for Pre-alloys & Granules include jewellery, soldering, brazing and micro-casting.
