Calculadora de peso da liga
Alloy Material Weight Calculator
说明：体积按环形截面面积 × 宽度计算（若输入厚度可用于长度估算，但本计算以 OD/ID/宽度 为准）。
对边距 = 六角形 flat-to-flat。面积公式 A = (√3 / 2) × a²。
注：The input unit is milímetros (comprimento), the density unit is g / cm³; The calculated result is the theoretical weight (kg), excluding processing loss and cutting allowance.
