" Highly polished kilogram and gram weights made of Troemner Alloy 8, a specially developed austenitic stainless steel that possesses closely controlled density, extremely low magnetic permeability, good stability, and resistance to corrosion and handling damage. This exclusive material has a density of 8.0 at 25°C (controlled to Â0.1%), is essentially nonmagnetic in the annealed condition, and will not transform to magnetic under any combination of temperature and cold work down to â"195.5°C (â"320°F). Fractional weights 500 mg to 5 mg are made of stainless steel (30 mg weights are made of aluminum) -fractional weights 3mg and below are made of aluminum. Weights 500 g and smaller are supplied in rugged polypropylene cases. Sets that include weights 1 kg and larger are supplied in oak, aluminum, or rugged plastic cases. All cases are fitted with individual compartments and marked with the accuracy class and serial number. A clear fitted cover secures the fractional weights within the case. Each case includes contoured weight forceps. Analytical weights 1g and above are manufactured with adjusting cavities. Standard weight sets are supplied with a Statement of Accuracy. Where applicable, weight sets are supplied with a NIST/NVLAP Weight Calibration Certificate or a Traceable Certificate.
