Manganese - high precision density-standard cube 1cm3 - 10.0 x 10.0 x10.0mm - purity 99.5% Made in Germany - The most accurate density standard cubes available! One of the most critical materials to work with. So the price is much higher than the material cost. Manganese - precision density-standard cube 1cm3 NEW! Using finest materials, each density cube was lapped to 10x10x10mm by a mechanical engineering company with an accuracy of 0.01 millimeter. Each one separately ground and polished it represents the theoretical density of the respective element by its weight. The weight is not affected by the laser inscription. Information such as element symbol, name and density is durable burned at the surface. Altogether 36 elements are available in a complete set in a wooden case (available separately). Manganese was discovered in 1774 by J.G. Grahn in Stockholm, Sweden. Manganese is abundant in the earth's crust (950 ppm) and its principle ore is pyrolusite, a crude form of the dioxide. It is obtained by reduction with aluminum or in a blast furnace. Pure manganese is a hard, brittle, silvery colored, metallic element which exists in three polymorphic forms (alpha, beta and gamma) and has a complicated crystal structure. It resembles iron in being moderately reactive and dissolving in cold, dilute non-oxidising acids. When exposed to air, manganese forms an extremely stable oxide coating which is not easily reduced. Pure manganese is ferromagnetic after processing. Manganese is not used as the basis of alloys but it is a common constituent of alloys based on other systems, its addition resulting in a significant improvement in the physical and mechanical properties of the resulting alloys. For example, it is present in all steels and cast iron, the concentration being increased for special grades of material; it is also added to certain grades of brass and bronze as well as some nickel and aluminum base alloys. Manganese is also an important element for living beings as manganese deficiency can result in weakened bones and cause them to be easily broken. On average, a human body will contain 12 mg of the element. scope of delivery You get one Manganese - precision density-standard cube 1cm3 shipping fees We calculate following shipping fees: Table of shipping fees: Standard International Airmail (5 - 10 days lead time)USA, Canada$26.90Asia, South America, Africa$31.50Australia, New Zealand, Oceania$37.00 Courier Express Services:Items up to 1kg (2.2lbs) by Courier Express (Very fast! 1 - 3 days lead time )USA, Canada$125.00Australia, New Zealand, Asia and other countries outside EU$152.30 Items over 1kg up to 2kg (4.4lbs) by Courier Express (Very fast! 1 - 3 days lead time ) USA, Canada$133.40Australia, New Zealand, Asia and other countries outside EU$169.70 I am happy to combine shipping to save you money!
