We have vast experience and an understanding of the techniques, processes, capabilities, and applications of products made from non-ferrous metals (zinc, lead, copper, and others) for different industries. We are constantly developing new products and applications to provide our final and intermediate customers with more added value.

Zinc Oxide

We are specialists in the production of ZINC OXIDE GOLD SEAL 99.9% - U.S.P. (United States Pharmaceope) and B.P. (British Pharmacoeia).

Our production is based on the French method using electrolytic zinc (Special High Grade - S. H. G. 99.995%). This procedure guarantees the best quality of the product for the appropriate use in the mining, pharmaceutical, plastic, glass, ceramic, paint, animal feed, phosphorus, cosmetics, rubber, electronic industries, among others.

Here are some of our zinc oxide characteristics:

  • It is insoluble in water, but soluble in diluted acids and bases.
  • It has piezoelectric and pyroelectric properties. The first one refers to the generation of electricity when mechanical stress is applied, while the second one refers to the generation of external electric currents when temperature changes.
  • Catalytic Property. In the hydrogenation of unsaturated hydrocarbons, a property used in the oil industry to obtain high-octane gasoline.
  • Semiconductor Property. It has a semiconductor property, which presents a small energetic difference between the occupied bands and the empty electron bands, occurring such conduction when an external energy is supplied to it that makes the electrons jump from one band to the other. Important applications are in varistors, thermistors and rectifiers.
  • It has a higher covering power than any other white pigment, due to its high refraction index. This characteristic is important in luminescent, photochemical, photoconductive and photovoltaic properties.
  • It offers good resistance to atmospheric changes, when applied to any surface.

We go deeper into the benefits of our flagship product in our blog, with the article titled Applications and uses of Zinc Oxide.

Copper Sulfate

We are specialists in the production of Copper Sulfate Pentahydrate. The quality of our raw materials, our standardized processes and physical-chemical control and analysis systems guarantee the quality of the product for the appropriate use in the industry.

In agriculture, it is used in pest mitigation. As a fungicide, it is effective in preventive treatments over different alternatives. It is also used as a bactericide, with the ability to attack certain fungi and bacteria. It is also used as a fertilizer, and because of its excellent solubility, it can be applied by sprinkler irrigation, drip irrigation, direct root injection, hose irrigation or foliar spraying.

It is used as an additive in animal feed to reduce copper deficiency, being a growth stimulant and the fattening of pigs and farm chickens. It prevents bone fragility and anemia in dairy cattle. It is a disinfectant and prevents bacteria, as well as an antiseptic and germicide in fungal infections.

It can be used as a mineral micronutrient and cupric catalyst in the production of pharmaceutical products as anti-microbial agents.

In the metallurgical industry, copper sulfate is usually used as a solution for galvanic baths, in the production of copper printed circuits (electric batteries) and in obtaining copper cathodes.

In mining, it is used in the flotation process for lead, zinc and cobalt separation, it is widely used in metallurgical processes as a sulfide activator of zinc, iron, cobalt and nickel, because of the ionic replacement of copper by zinc.

Copper sulfate is also present in the pharmaceutical industry, where it acts as a mineral micronutrient and copper catalyst in the making of products such as anti-microbial agents.

Properties of Copper Sulfate:

  • Appearance: Blue crystals.
  • Odour: No odour
  • Specific gravity 15°C 2,28g/ml.
  • Solubility 22 g/100g H2O at 25°C
  • Boiling point at 110°C decomposes.
  • PH: Solution 3.5-4.5

It is a zinc, aluminum, magnesium and copper alloy. This alloy, depending on the percentages and final uses, can be ZAMAC 2, 3, 5, 7, Tonsul and other formulations according to your requirements.

Zamac, or zamak, by its initials in German, is used in the elaboration of auto parts, home appliances, toys, zippers, carburetors, automobile oil pumps, automobile handles, plates or logos, bathroom and toilet articles, fan frames, computers, camera components, refrigerator handles, gas regulators, shelves, hardware, buckles, ornaments, candlesticks, trophies, among others.

Zinc alloys are used for injection molding and die casting, depending on the amount of alloying elements it possesses, can have different properties for a given use. The most common are the following :

  • Zamac 2: It is an alloy used for injection molding that offers the highest resistance and hardness; however, its high copper content (3%) generates changes in its properties during prolonged use: dimensional growth 0.0014 mm/mm in 20 years, lower elongation and decrease in resistance. It has excellent castability and is used in injection and gravity casting, it maintains resistance and hardness in aging, it can be used for friction parts avoiding the use of inserts or bushings in the designs.
  • Zamac 3: Recommended for pressure injection molding, it has good castability and great dimensional stability, excellent balance between physical and mechanical properties. The surface finish is ideal for final coatings for electroplating, painting and other surface treatments. It is the most recommended zinc alloy for pressure injection.
  • Zamac 5: It has a higher hardness and resistance than Zamac 3, this is due to the higher content of Cu (1%), it presents a better behavior than Zamac 3 against deformations in time (creep). It is commonly used for injection, with excellent casting characteristics. Due to its greater hardness and mechanical resistance, it can be applied in less thickness, thus achieving the same mechanics as Zamac 3 and with a good superficial finish.
  • Zamac 7: It offers better fluidity due to the lower content of magnesium and the addition of nickel. For this reason, it is used for thinner wall designs. It has greater ductility than Zamac 3, which is ideal for situations that require plastic deformation for the subsequent assembly of the parts.
