6-6-NTLM Chinese Door Lock Set: Revolutionizing Security with Aluminum Construction & Computer Key Technology

The Evolution of Chinese Standard Door Hardware

In the rapidly growing architectural hardware market, Chinese-standard door locks have emerged as a global benchmark for security and durability. The 6-6-NTLM Plate Lock Set represents the pinnacle of this evolution, combining precision engineering with advanced materials science. Designed specifically for commercial and residential applications requiring Chinese dimensional specifications, this lock set features a robust 50mm mortise lock body paired with a 70mm high-security cylinder – the exact measurements required for seamless integration with Chinese-manufactured doors.

Engineering Excellence: Aircraft-Grade Aluminum Construction

Unlike traditional brass or steel locks, the 6-6-NTLM utilizes aerospace-grade aluminum alloy that delivers exceptional benefits:

  • Corrosion resistance: Withstands coastal humidity and industrial environments
  • Weight reduction: 30% lighter than brass equivalents
  • Structural integrity: Maintains tolerance under extreme temperature fluctuations
  • Sustainability: Fully recyclable material with lower carbon footprint

Computer Key Technology: The Future of Access Control

Included with each set are three computer keys featuring advanced security protocols:

Feature Benefit
Restricted keyways Prevents unauthorized duplication
Master key systems Simplifies facility management
Anti-pick pins Thwarts lock manipulation

PVD Finishes: Beauty That Endures

The gold and black nickel finishes aren’t merely cosmetic – they’re applied using Physical Vapor Deposition technology that creates surfaces 5x harder than traditional electroplating. This process bonds the coating at molecular level, ensuring:

  • 500+ hours salt spray resistance
  • UV fade protection
  • Fingerprint resistance
  • Consistent coloration depth

Commercial Applications & Value Proposition

For property developers and facility managers, the 6-6-NTLM delivers quantifiable advantages:
