| QC7 ALUMINIUM ALLOY * | 2.833 | 167HB | 91 | 74-79 |
| STANDARD ALUMINIUM | 2.722 | 95HB | 96 | 40-42 |

| H13 QUALITY TOOL STEEL | 7.777 | 52-54RW | 14.4 | 228 |
Note 1 - HB=Brinell, RW=Rockwell. Higher numbers indicate increased hardness levels. Note 2 - Values in BTU/[(Ft.² Hr.°F)/Ft.] at 68°F - higher numbers=greater thermal conductivity. Note 3 - *=Alternatives to QC7 with very similar characteristics may sometimes be used. |
| These specifications provide many benefits and ultimately, enable us to make production quality alloy mould tools & mouldings for you in less time & at lower cost than our competitors. |
| 5 reasons why alloy mould tools are better than steel mould tools |
| » Easier to machine/polish - higher cost savings, shorter deliveries & simpler modifications. |
| » 4 x thermal conductivity of steel - better tool heat dissipation & thus, faster cycle times |
| » Closer to tool temp. ejection - less stress, distortion, warpage & post mould shrinkage |
| » Excellent consistency & experience of 200+ mould tools - we'll guarantee your tool life |
| » 1/3 weight of steel - reduced machine energy use & staff fatigue loading tools/inserts |
