When it comes to choosing the right cable for your aircraft or pulley system, two popular options are stainless steel and galvanized steel. Both types have their advantages and disadvantages, which are crucial to consider before making a decision.

One of the main differences between stainless steel and galvanized steel cables is their friction coefficient. Stainless steel has a higher friction coefficient, which means it experiences increased wear every time it's flexed. This can lead to a shorter service life compared to galvanized steel cables. On the other hand, stainless steel is more corrosion-resistant than galvanized steel.

Galvanized steel cables, on the other hand, are easier to inspect for corrosion damage and have greater fatigue strength. They also tend to be stronger than stainless steel cables of the same size. However, they can corrode over time, which can compromise their integrity.

In general aviation aircraft, control cables are typically made from either stainless steel or galvanized steel. While there are pros and cons to each material, most pilots and maintenance personnel would agree that both types can serve the purpose well.

Interestingly, many aircraft cables move very little, with only a short section of cable moving over each pulley at any given time. This means that the wear on the cable is often concentrated in a specific area, rather than being evenly distributed throughout its length. Galvanized steel cables have an added benefit here, as the zinc coating acts as a natural lubricant between the fibers, reducing friction and wear.

In recent years, studies have shown that stainless steel cables are more prone to fraying than galvanized steel cables due to the individual wires rubbing on each other. This has led some manufacturers to favor galvanized steel cables for their aircraft control systems.

For those who are looking for a specific example of cable strength, it's worth noting that 1/8' 304 stainless steel cable has a break strength of 1760 pounds. Galvanized steel cables tend to be slightly stronger in this regard.

In conclusion, while both stainless steel and galvanized steel cables have their advantages and disadvantages, the choice between them ultimately depends on your specific needs and requirements. By considering factors such as corrosion resistance, fatigue strength, and wear patterns, you can make an informed decision about which type of cable is best for your aircraft or pulley system.
