We'll be frank, currently most of the backplates sold in the US under various brand names, including many we sell, are actually manufactured in China by companies specializing in metalworking then imported in to the US. There is no difference in quality between the various styles and brands we sell, in our long experience they are all equally good quality.
咋不顺便把双瓶的也做了。。
双气瓶的是两个园框夹着气瓶，要求尺寸要准确，没具体尺寸。。。
而且考虑用后背双瓶不如用测挂方式。
生锈的时候计算下是多少潜，嘻嘻～
国内的材料...外加表面工艺...不是很靠谱......
铝合金的，生锈是很难很难的。做工很好。一般数控机床能达到的精度已经是微米单位了，愿意为了一块铁，几个洞多付几倍价格的也大有人在。有钱是好事，舍近求远也是一种乐趣。
铝合金不做表面处理遇海水很快就氧化的。。
加工精度不是主要问题.....
感觉...主要问题是金属材料和表面处理工艺...国内的很多不锈钢都是会生锈的...> <..不比进口的材料...
外加..表面处理工艺.差距还是有的...
...不过看图还是很漂亮的～.100rmb的定购感觉好便宜啊...> <...我都想叫自家供应商给我做相机握把..感觉很好玩～
关于海水腐蚀是这样的
316L的双相不锈钢绝对不受海水腐蚀，放心使用
铝都会被腐蚀，包括5056，要氧化处理的
简单百度了一下...> <.
.双相不锈钢....请教加工起来是否方便..> <
316L 是不是那些经常被做首饰的，还有些家伙叫钛钢的！
在divegearexpress网站上看到，其实多数大牌的钢板或铝板产品也都是天朝制造的，只是这些工厂没顾上内销市场
