由于陶瓷和金合金之间膨胀系数不匹配（Δα）而产生的热剪切应力可能超过13000 psi的剪切阻力。因此，进行了Aa公差的计算。Aa值为0.125 X 10-6英寸/英寸/华氏度是安全的。
Thermal shear stresses that arise from a mismatch of expansion coefficients (Δα) between porcelain and gold alloy can exceed the 13,000 psi shear resistance of the bond. Therefore, calculations of the Aa tolerance were made. A Aa of 0.125 X 10-6 inch/inch/degrees F is safe.
