Because of their thin profile, these boards are ideal for trim, furniture accents, and indoor projects rather than heavy structural framing. 2. Chemical Science: Sodium (Na) Ratios
materials, the structure is notable for not undergoing a major phase change during ion extraction, which leads to a very small volume change (less than 4%) and better battery longevity. An/Na: 1x4
In woodworking and construction, a refers to a specific size of board. The "An/Na" in this context often refers to Actual vs. Nominal sizing. Because of their thin profile, these boards are
