外来vs. Aluminum
The key features of外来®fiberglass structural shapesare compared against aluminum extruded shapes in the following table:
| 特征 |
外来®玻璃纤维结构形状 |
Aluminum Extruded Shapes |
| CORROSION RESISTANCE |
Superior resistance to a broad range of chemicals.
Surfacing veil and UV additives improve weatherability. |
Can cause galvanic corrosion.
通过阳极氧化或其他涂层可以增加耐腐蚀性。 |
| 重量 |
非常轻巧 - 铝的重量约为80％。 |
轻量级 - 约1/3铜或钢。 |
| 电导率 |
Insulates — low thermal conductivity (4 btu/sf/hr/f°/in); low thermal coefficient of expansion (7 (in/in/f°)106). |
Heat conductor — high thermal conductivity (150 btu/sf/hr/fo/in); thermal coefficient of expansion 11-13 (in/in/f°) 106。 |
| STRENGTH |
终极弯曲强度（FU）LW = 30 KSI，CW = 10 KSI。
外来®has 86% of the yield strength of aluminum and pound-for-pound, is stronger than aluminum in the lengthwise direction. |
弯曲强度（FU）35 KSI。
Homogeneous material. |
| FINISHING AND COLOR |
Pigments added to the resin provide color throughout the part. Special colors available. Composite design can be customized for required finishes. |
银色。其他颜色需要预先限制，阳极涂料和油漆。可以应用机械，化学和电镀术。 |
| EMI/RFI TRANSPARENCY |
Transparent to radio waves, EMI/RFI transmissions; used for radar and antennae enclosures and supports. |
高度反思。 |
| FABRICATION |
易于使用简单的木匠工具的田间制造 - 使用粘合键合和/或机械连接。没有火炬或焊接。 |
Good machinability — welding, brazing, soldering or mechanical joining. |
| COST |
工具成本略高；每只直线英尺的价格略高。 |
挤出工具相对便宜。零件价格可比或略低。 |
| 冲击阻力 |
外玻璃垫子®distributes impact load to prevent surface damage even in sub-zero temperatures. Will not permanently deform under impact. |
在影响下很容易变形。 |
