Like all products, Rose +Bopla’s cast aluminum enclosures do have limitations. Rose+Bopla cannot change the size of any of these boxes dimensionally. Rose +Bopla’s die cast boxes have depth limitations. Most designs are somewhat shallow. Rose +Bopla cannot increase depth. If depth is a problem, use Rose+Bopla’s Build-A-Box®enclosures which are made from aluminum extrusion that can be cut to any depth required. If you cannot find the size you need, please call the factory. We can do a custom size for your application. Tooling costs and minimum order may apply. Rose +Bopla uses AL Si 12 alloy in its cast aluminum housings. The term “Copper Free” is used to describe aluminum alloys which contain less then 0.4% copper. Rose +Bopla’s copper content is .10% for Die Castings and .05% for Chill Castings and Sand Castings. It is the reduction in the copper content which increases the natural corrosion resistant properties of aluminum. Copper Free aluminum is particularly resistant to salt atmospheres, sulphur gases and ammonium nitrate. Above a level of 0.4% copper, the range of corrosion due to galvanic action within the structure of the metal increases rapidly. Rose +Bopla’s aluminum alloys are highly superior to most ferrous materials. For military applications we irridite these enclosures to Mil Spec C-5541, Class 1A or Class 3. Rose +Bopla’s “Copper Free” aluminum products provide optimum protection against galvanic corrosion. 130 240 1 60 2.65 Very Good Good Good Limited 18-27 130-160 200 -100 80 170 6 55 2.65 Excellent Adequate Good Excellent 18-27 140-170 200 -100 70 150 5 45 2.65 Excellent Adequate Good Excellent 18-27 140-170 200 -100 160 215 12 70 2.7 - Excellent Excellent Excellent 28-34 190-210 200 -100 N/mm2 N/mm2 % HB g/cm3 m/ mm2 W/mK °C °C Pressure Die-Cast Chill Cast Sand Cast Extrusion Unit Of Measurement |
