Solid Eco ice-melt

Aluminium, brass, steel and copper were immersed in a 2.5% solution of the de-icer for 14 days to
determine its effects on the materials.

Metal	Total Immersion Corrosion (mils per year)	Limits (mils per year)
Mild Steel	0.1	10
Aluminium	0.3	10
Brass	0.2	5
Copper	0.3	5

Liquid Eco ice-melt

Aluminium, brass, steel and copper were immersed in the liquid de-icer for 14 days to determine its
effects on the materials.

Metal	Total Immersion Corrosion (mils per year)	Limits (mils per year)
Mild Steel	0.2	10
Aluminium	0.2	10
Brass	0.3	5
Copper	0.3	5
