Brass weights are essentially non magnetic, but can be effected slightly by magnetic fields. Brass weights should not be used as precision reference standards due to daily weight variations with atmospheric air density (air buoyancy), wear and contamination. They should not be used to calibrate precision balances. Brass weights should be re-calibrated annually.

Common weights used for standard precision balances and scales.
Brass weights are essentially non magnetic, have better short term (daily to monthly) weight stability.
Brass weights have better short term (daily to monthly) weight stability than cast iron, but will vary with time due to wear and corrosion of the brass and lead adjusting slug. With light use and good storage and handling, they will retain their value to within ½ to ¼ of the original tolerance over many years. As brass is a soft material, regular use will cause the weight value to reduce more quickly through wear. Brass weights are essentially non magnetic, but can be effected slightly by magnetic fields.
