Perhaps the most important property people mention when comparing iron to bronze is hardness. Hardened steel will greatly outperform bronze. Iron will not.

Bronze with 8% tin will have a hardness of about 90HV annealed, and about 200HV work-hardened. Bronze with 20% tin (as used, e.g., in Chinese bronze blade) will be about 200HV as-cast (don't have a value for work-hardened - IIRC these high-tin bronzes can't be cold forged).

Wrought iron, if there are no alloying elements increasing work-hardenability, will be about 80HV annealed and 200HV work-hardened. Greenland telluric iron tools/weapons are usually from 190HV to 230HV. Greenland meteoric iron will reach 200HV to 340HV.

As far as other properties go,

• iron is stiffer, and less dense, and an iron blade can be about 2/3 the weight for the same stiffness (assuming only the thickness is changed)

• bronze is more corrosion resistant

• bronze is much easier to cast (much lower melting point)
