The ULTEM Advantage: Technical Performance

Why "Tungsten Titanium"? Understanding the Name

The term "Tungsten Titanium" (钨钛) is a marketing name commonly used in Asian markets to describe ULTEM/PEI material . It's important to understand:

• Not actually containing tungsten or titanium—it's a high-performance polymer

• The name reflects the material's exceptional properties: strength like tungsten, lightness like titanium

• Also known as: "Plastic Steel" (塑钢), "ULTEM," "PEI," "Aerospace Material"

For the 6517, this naming convention helps bridge the gap between its vintage-inspired appearance and its thoroughly modern material science.

The 6517 Design Story

The MOODISH 6517 draws inspiration from the golden age of optical design—the 1950s and 1960s when eyewear first became a fashion accessory. Key design elements include:

• Period-accurate proportions: Authentic 51mm size that defined an era

• Refined browline: Subtle thickness variation that echoes mid-century craftsmanship

• Clean geometric form: Free from unnecessary ornamentation

• Timeless versatility: Equally suited for period costume or contemporary style

Yet beneath this vintage exterior beats the heart of 21st-century materials science—ULTEM polymer that would have seemed like science fiction to the original designers of these classic forms.
