The invention relates to a high-temperature forming tool (1), the high-temperature forming tool (1) being at least partially composed of a molybdenum-based alloy having a molybdenum content of > = 90% by weight, the molybdenum-based alloy being provided in a pressed and sintered state and having a thermal shock resistance of at least 250 K when in the pressed and sintered state, the thermal shock resistance being defined as the quotient of ReH/(alpha * E), wherein ReH is the yield point at room temperature in MPa, alpha is the coefficient of thermal expansion in 1/K, and E is the elastic modulus in MPa. 本发明涉及一种高温成型工具(1)，其中高温成型工具(1)至少部分地由具有钼含量为≥90重量％的钼基合金组成，其中钼基合金以压制和烧结状态提供，并且在处于压制和烧结状态时具有至少250K的抗热震性，该抗热震性定义为ReH/(α·E)的商，其中ReH是室温下的屈服点，单位为MPa，α是热膨胀系数，单位为1/K，并且E是弹性模量，单位为MPa。
