1. General information
Characteristics:
Crystalline, brittle metal, with reddish tinge. Soluble in nitric and hydrochloric acids. Highly diamagnetic (mass susceptibility -1.35 X 106). Expands 3.3% on solidification. Electrical resistivity higher in solid than in liquid state. Extrudable at 437 oF, not fabricable at room temperature. Brinell hardness 7. Thermal conductivity is lowest of all metals except mercury. On heating it burns to form the oxide
Applications:
BISMUTH could be used in different fields, according to its purity. Bismuth has a low thermal conductivity and is both stable and non-toxic. These properties make the metal an ideal substitute for lead in everything from pipes and bullets to fishing weights and sprinkler triggers. High purity bismuth is used to synthesize pharmaceutical chemicals, superconductive ceramics and oxide crystals for the production of bismuth ortho-germanate crystals.

Needle Punching is a non-woven product that has high durability, strength and density. Needle Punching is a textile made of polymer material, which is water permeable, in the form of woven, knitted or non-woven (non-woven) used by geotechnical and civil engineering. Non Woven Geotextile (Non Woven) is a non- woven geotextile, the process of joining the forming fibers occurs due to a mechanical process by puncture of small needles or united by heat. It has been widely used for air filter, automotive and other applications. Almost all famous car brands have used our products. Our advantage is the strong damping power to perfectly dampen the sound vibrations of the engine, so that driving is comfortable.

Tailoring needles are specialized tools used in the art of sewing and garment construction.They are designed with a sharp point and a long, slender body, allowing for precise and controlled stitching. Tailoring needles come in various sizes and types. They are typically made from high-quality materials such as aluminum (anodized), stainless steel or nickel-plated steel, ensuring durability and resistance to corrosion. The needles are often categorized based on their size, indicated by a numerical system. Smaller numbers denote larger needle sizes, while larger numbers represent finer needles. The size of the needle depends on factors such as the thickness of the fabric, thread type, and desired stitch length.
