Copper is a metal that is solid under normal conditions of temperature and pressure. It has a metallic shine and a reddish or brownish color. The use of copper for the production of objects and tools dates back to 8,000 BC. This is due to its native form, its easy handling, and its metallic properties such as conductivity and resistance.

It is resistant to corrosion and high temperatures, and is also a good conductor of electricity and heat. Its main applications are in electronic materials, wires and cables for energy transmission, pipes for gas and hot water, and metal alloys such as brass and bronze (used in instruments, for example).

TYPES: Red copper, honey copper, first copper, ground red copper, copper stamping, punched copper, clean copper tubes, copper busbars without paint or dirt, enameled and mixed copper, burned copper, second copper, mixed ground copper, and painted copper busbars.

A series of metal alloys based on copper and tin with varying proportions of other elements such as zinc, aluminum, antimony, nickel, phosphorus, lead, among others, in order to obtain superior characteristics to those of copper. Bronze was used for the first metal weapons and tools, as well as for the production of statues. When polished, this material can reach a golden yellow color and it is the most used material in the field of sculpture due to its enormous structural resistance, resistance to atmospheric corrosion, ease of casting, and finishing capabilities that allow excellent polishing or the use of different colors and types.

TYPES: Bronze scrap, bronze chips...

A metal alloy composed of copper (Cu) and zinc (Zn) atoms. Used since prehistoric times, brass has a shine similar to gold, is quite malleable (can be easily molded into very thin sheets and plates), ductile (can be reduced into wires), a good conductor of heat and electricity, and presents significant resistance to corrosion and mechanical shocks. Thus, brass can be forged, cast, rolled and cold drawn more easily than copper and zinc separately. The uses of brass are vast and comprise a series of industrial segments. This metal alloy is applied, for example, to the manufacturing of condenser tubes, firearms, ammunition cartridges, faucets, rivets, radiator cores, wind instruments, medical and surgical instruments, ornaments, jewelry and costume jewelry, electrical terminals, pots and pans, coins, screws, wires, bars, valves, wheels for cars, among others.

TYPES: Brass hydrometer, wire EDM, brass stamping, brass tubes, brass tip, shavings, brass radiators, and mixed brass scrap.

Cupronickel is a copper-nickel alloy with up to 30% nickel. It offers good resistance to corrosion and fatigue, commonly used in the manufacturing of coins, condensers, and distillation equipment.

TYPES: Cupronickel 90/10 or 70/30.

Aluminum is a lightweight, soft and strong metal. It has a silver-gray and matte appearance due to the thin layer of oxides that quickly form when exposed to air. Its lightness, electrical conductivity, corrosion resistance, and low melting point give it a multitude of applications, especially in aerospace engineering solutions. Aluminum is non-toxic as a metal, non-magnetic, and does not create sparks when exposed to friction. Its density is approximately one-third that of steel or copper. It is very malleable, very ductile, suitable for machining and casting, in addition to having excellent resistance to corrosion and durability due to the protective oxide layer. It is the second most malleable metal, with gold being the first, and the sixth most ductile. Being a good heat conductor, it is widely used in kitchen pots and pans.

TYPES: Clean block, aluminum radiator, painted aluminum profile, aluminum chips, mixed block, among others...

Stainless steel, also known as inox steel or inox, is a metal alloy composed of iron, chromium, carbon, and nickel that is highly resistant to corrosion and heat. Depending on the application, other elements such as silicon, titanium, niobium, molybdenum, cobalt, boron, and nitrogen may also be added to improve its basic characteristics. While ordinary steels rust, stainless steel is generally highly resistant to corrosion. The responsible element for this resistance is chromium, which, depending on the amount in its composition, when in contact with oxygen, forms a protective film on the surface of the steel, making it impermeable. Stainless steel must contain at least 10.50% chromium. The addition of nickel to stainless steel gives it ductility, allowing it to be worked on its surface, as well as resistance to high temperatures and weldability, improving its overall strength. Generally applied in: Hospital facilities; Cutlery segments (utensils, pans, trays); Sanitary equipment, sinks, and furniture; Elevator coatings; Stair railings; Home appliances (stove, refrigerator, microwave); Car parts; Nautical equipment; Civil construction.

TYPES: Stainless steel scrap, stainless steel shavings, among others...

Zamac is a zinc alloy that contains aluminum, magnesium, and copper. It has good resistance and deformability when defining the metal, and can be used in various ways, such as chrome-plated, painted, and even machined, depending on the intended use.

Zamac can be classified into three types of alloys: 3/5/8, according to the percentage of the elements in its composition. Each alloy provides the best combination of properties, but as the properties increase, there is a reduction in its ductility.

TYPES: Zamac dross, zamac shavings, uncoated zamac, mixed zamac scrap, and chrome-plated zamac.
