A new metal foam having similar elasticity as bone has been crafted by the scientists of North Carolina. This marks a new invention in the field of biomedical implants and could replace the old titanium often having chances of rejection. This metal bone is claimed to be lighter compared to solid aluminium and is made of 100% solid steel. The metal foam’s astonishing high-energy absorption facility and light weight makes it comparable to bone. Modulus of elasticity of a material gauges its capability to distort when pressure is applied and then goes back to its original shape when pressure is withdrawn.The uneven surface of the foam may also promote bone development into the implant, thereby enhancing the power of the implant.
