* 7 Wheels refers to a Japanese Clan Name* 7 shichi / nana / nana-tsu / nano* Wheel rin / wa_______________I‘m guessing it would look something like this? :Romaji : NanaWaKana : 七輪
Aluminum profiles are extruded, in simple terms Aluminum when heated to a certain state is pushed through a hole of the shape that you require and out pops your window frame profile or whatever, in theory this can be done to an infinate length Copper pipe is similar, but it is forced thorough a die which has spokes to support the central die, i believe as the copper is parted to go around the central die it is still maleable enough to fuse together on the other side, if you can picture that you are doing well!!
That's technically right, but shichirin is also something you cook on, just as an FYI. But as shichi/nanarin Wa isn't the counter for wheels, rin is. Wa is the noun and in Japanese when counting something you don't always say eight cats you usually say 8 animals of cats because you use a special animal counter with the number.
7 wheels nanatsu no sharin (vehicle) nanatsu no wa (ring) nanatsu no handoru (steering wheel) Q : how many wheels? A : 7 Q : sharin wa ikutsu aru no? A : shichirin (shichi seven, rin is counter for wheel) we dont use 'nanarin' or 'shichirin' when we say '7 wheels'. that's gonna be a answer for question like above.
Copper, in small amounts, isn't harmful. Once a layer of patina has been created, it doesn't strongly react to the water. It's bendable. It's easy to solder parts together. Strong (can withstand high water pressures without bursting, but that's true of many metels).
Easy to maneuver, fairly bendable (up to 3 degree's at a min of 300', that's actually very good), chemical wise it is safe with water (wont rust, wont chip, water is drinkable when it goes through it), compared to other metals it's cheap. Copper is becoming more expensive compared to plastics and other mostly man made things so they are switching to something that's closer to plastic. Something more common is High Density Poly Ethel (HDPE). It's what just about everyone has switched to. Worked for a civil engineering place as a drafter (had to look up material costs).
