铝末混合炸药（Torpex）是比TNT更强50%的次级炸药（secondary explosive），。Torpex是由42%的RDX、40%的TNT和18%铝粉混合而成，它自1942年下半年起用于第二次世界大战，其名称来源于鱼雷炸药（ 'Torpedo Explosive'）的缩写，它原来是为了用于鱼雷而开发的。Torpex在水下军火开发上发挥了重要作用。

由于其包括铝能使爆炸脉冲持续更长，增大了破坏力。它经常用于重要的军火中，如鱼雷、Upkeep、Tallboy和Grand Slam炸弹中，它也被用于阿佛洛狄忒行动（Operation Aphrodite）中的无人机上。Torpex很早就被H6和PBX炸药组份所取代，它已经被废弃。所以除了在遗存军火或未爆炸弹中，Torpex已经很少见了。

Torpex is a secondary explosive 50% more powerful than TNT by mass. Torpex comprises 42% RDX, 40% TNT and 18% powdered aluminium. It was used in the Second World War from late 1942. The name is short for 'Torpedo Explosive', having been originally developed for use in torpedoes. Torpex proved to be particularly useful in underwater munitions because the aluminium component had the effect of making the explosive pulse last longer, which increased the destructive power. Torpex was used only in critical applications, e.g. torpedoes and the Upkeep, Tallboy and Grand Slam bombs. It was also used in the Operation Aphrodite drones. Torpex has long been superseded by H6 and PBX compositions. It is therefore regarded as obsolete, so Torpex is unlikely to be encountered except in old munitions or unexploded ordnance.
