Common Challenges of Phosphor Bronze PB102 & PB103
While PB102 and PB103 offer excellent performance, they also come with some challenges or “pain hooks” to consider:
1. Higher Material Costs:
Phosphor Bronze alloys are more expensive than other common metals like brass, making them less ideal for budget-sensitive projects.
2. Limited High-Temperature Performance:
PB102 is not suitable for high-temperature environments, where other materials like stainless steel or nickel alloys may perform better.
3. Work Hardening:
PB102 can become harder to machine as it undergoes work hardening, increasing production costs and time.
1. Even Higher Costs:
PB103 is more expensive than PB102 due to its higher tin content, which may be a drawback for cost-conscious buyers.
2. Machining Difficulty:
The added strength in PB103 makes it more challenging to machine, which can lead to higher tooling and labour costs.
3. Weight Considerations:
PB103’s higher density means it is heavier, making it less ideal for applications where weight is a critical factor, such as aerospace or automotive components.
