From what I gathered researching before purchase is that they switched to zinc due to it being more accurate with molding. Sharper lines and in general less imperfections than can be achieved with aluminum castings. I read somewhere also that zinc is cheap, but prices are 1¢ off from aluminum so I doubt that was much of a determining factor. I like the weight, just hate to find out what it would do when dropped on a foot or a floor. Battery life seems great for running a .27 build. Ergonomically I really like the fire button and the curves where your fingers naturally rest. Don't think I can use a regular box anymore after this!
Earlier in this thread: SXmini M Class (TEMP CONTROL) A quick google search yields: Zinc die casting has tighter tolerances than Aluminum or plastic die casting, which often eliminates the need for additional machining. When no additional machining is needed, it’s called “Zero Machining” manufacturing. This is one of the major advantages of Zinc die casting. Because Aluminum has to be so much hotter than Zinc, the thermal shock from being put in a die produces a part with a surface that can be more pitted. Chrome finish amplifies every defect in a part, which makes Zinc much easier to finish compared to Aluminum. Zinc die casts can be easily polished, plated, painted, chromated or anodized. Zinc alloys are some of the strongest and toughest materials for die casting. Neither plastic, gray cast iron, or Aluminum withstand impacts as well as Zinc alloys do. Zinc melts at 787.2°F whereas Aluminum melts at 1,221°F. This gives Zinc an advantage because casting can use a process called “Hot Chamber” casting which is quicker as well as being less costly than “Cold Chamber” methods.Interesting, where did you find that info? I use to work in aluminum die casting and we made tons of stuff but I have no experience in zinc. Yes, I agree I would hate to drop on my foot. I like the fire button too. I can tell a lot of thought went into the design of the ML. I think it's the best mini mod on the market.
They didn't switch to zinc. You would've thought they would've learned that the paint doesn't stick well to zinc without an expensive process. Didn't any of you have the M class. The M and as far as I know the S is zinc alloy also. These look as if they are a little bigger so heavier then the M not sure why they made them bigger since the chip is the same size as the M. The M is also heavy for it's size. I think they have gotten better on the finish from the first M's but I would be really careful with them till they come out with the sleeve and wait for the one made by YiHi. They came out with one for the M before YiHi's and it wasn't nearly as good. The J wrap is another option but not sure how it would fit on the ML with the ribs. I have 5 M's the 3 I use are Jwrapped and sleeved. Best Tc Mod I have used but haven't tried the DNA yet. Haven't really seen one that blows my dress up. Don't like the idea of sending it in to have the battery changed and have absolutely no use for 200w. The M does everything the ML does except for the software. If you have decided on one wire the M is every bit as good as the ML. You still have the choices with the manual TCR setting and compensate temp. NI200 mode and Ti mode that are right on.
Wasn't the older version of the battery tube made of brass? If so, stainless is lighter than brass.
