Bronze swords represent the pinnacle of pre-iron weapon technology. Casting a long blade required precise control of the copper-tin alloy ratio (typically ~10% tin), mould design, and cooling rate. This metallurgical knowledge, developed over centuries of empirical practice, represents one of the great achievements of ancient technology.
