BORON AS AN ADDITIVE TO STRENGTHEN STEEL AND ALUMINUM ALLOY
Steel is the most useful construction material. It's strong, durable and versatile but it has some limitations too like being susceptible to corrosion from water or air exposure.
As well as having a low ductility which makes it brittle at cold temperatures so if you drop your steel sheet on the floor there's a good chance that someone else might break their foot because its thinness allows for more impact before breaking apart even with small drops of weight!
