Copper Products

Lester Metals offers premium copper products including foil, sheet, plate and bar in rolls and sheets slit to your specifications. The thickness or gauge of the material is what determines whether is is called foil, sheet or plate. Copper foil material thickness ranges from .0005" to .0079". Copper sheet material thickness ranges from .008" to .0125". Copper plate and bar material thickness ranges from .0125" to 5.00".

 

We offer high quality and fast shipping on both large and small quantities for many applications including arts and crafts, electrical, embossing, flashing, manufacturing and research and development.

About Copper

Copper is a ductile metal with very high thermal and electrical conductivity. Pure copper is rather soft and malleable and a freshly exposed surface has a pinkish or peach color. It is used as a thermal conductor, and electrical conductor, a building material, and a constituent of various metal alloys. Copper metal and alloys have been used for thousands of years and was principally mined in Cyprus. Today some countries such as Chile and the United States still have sizable reserves of the metal which are extracted through large open pit mines. However, there is a concern that the copper reserves may be insufficient to sustain the current high rate of copper consumption.

 

Decorative Uses: Copper compounds are known in serveral oxidation states, ususally +2, where they often impart blue or green colors to natural minerals such as turquoise and have been used historically widely as pigments. Copper metal architectural structures and staturary eventually corrode to acquire a characteristic green patina. Copper as both metal and pigmented salt, has a significant presence in decorative art.

 

Anti-Bacterial & Antimicrobial Properties: Copper (II) ions (Cu2+) are soluble in water, where they function at low concentration as bacteriostatic substances, fungicides, and wood preservatives. For this reason, copper metal can be used as a anti-germ surface thta can add to the anti-bacteriall and antimicrobial features of buildings such as hospitals. In sufficient amounts, copper salts can be poisonous to higher organisms as well. However, despite universal toxicity at high concentrations, the Cu2+ ion at lower concentrations is an essential trace nutrient to all higher plant and animal life. In animals, including humans, it is found widely in tissues, with concentration in liver, muscle and bone. It functions as a co-factor in various enzumes and in copper-based pigments.

 

Mechanical Properties of Copper: Copper is easily worked being both ductile and malleable. The ease with which it can be drawn into wire makes it useful for electrical work, in addition to its excellent electrical properties. Copper can be machined, althought it is usually necessary to use an alloy for intricate parts such as threaded components to get really good machinability characteristics. Good thermal conduction makes it useful for heatsinnks and in heat exchangers. Copper has good corrosion resistance, but not as good as gold. It has excellent brazing and soldering properties and can also be welded, although best results are obtained with gas metal arc welding.
