1,Description:
Copper is a transition metal characterised by high electrical and thermal conductivity, excellent ductility, corrosion resistance and ease of machining.
Physical properties
Copper is purplish-red in colour and soft in texture; it possesses good ductility and malleability, and can be formed into various shapes through processes such as forging, extrusion, rolling and drawing.
. It has a moderate density, a specific gravity greater than that of iron, and does not become brittle at low temperatures
. Copper ranks among the top metals in terms of electrical and thermal conductivity, second only to silver, and is therefore widely used in wires, cables, electronic components and heat exchangers
Chemical Properties
Copper has low chemical reactivity and is insoluble in non-oxidising acids at room temperature; however, it can be oxidised to form a protective layer of copper oxide (verdigris), thereby enhancing its corrosion resistance.
. Copper and its alloys exhibit good resistance to corrosion by media such as air, water vapour, dilute brine, low-concentration organic acids and ammonia, and can be used in corrosive environments such as marine and chemical industries
. Furthermore, copper is an essential trace element for the human body and plays a vital role in the health of the blood, nervous system, immune system, as well as bones, skin and internal organs.
3,Technical Advantages
Hot-dip Yellow Zinc Plated Mild Steel composition: 0.15%-0.20% low carbon iron steel, surface thick yellow chromate zinc passivation layer. Material maintenance rules: Economical anti-rust coating for indoor pump use; wipe workshop oil mist attachment regularly; avoid long-term immersion in running water; store finished bolts in moisture-proof carton; tighten bolts regularly to compensate vibration loosening; re-spray zinc anti-rust paint for surface scratch positions to prolong service life.
Available in small packing, carton packing, or pallet configurations to meet your shipping and storage requirements.
Manufactured by JIA SHAN Hardware Company with strict quality control measures and pre-shipment inspection.
